TRAITS \nPersonal Characteristics, things about you such as eye-color, skin color and blood-type that are special.\n\n\nINHERITED \nTraits passed down from your parents. (Traits that you were born with.)\n\n\nACQUIRED \nTraits such as pierced ears, hair length, scars, etc. that you were not born with.

NO bulimia is not inheritable, but lemme expand on chi_o_dawnie's answer.\n\nThere are some psychological tendencies that people have which are somewhat heritable. For example, some people have highly addictive personalities. They may have extensive histories of alcoholism. Is alcoholism it inherited? No, it's not. But that person whose from a family of alcoholics can inherit the tendency to become addicted to alcohol. But if and only they begin drinking a lot! If that person never drinks, then they can never be an alcoholic.\n\nSame with bulimia. If you inherit the kind of tendencies that compel you to exercise extreme control over things like your *weight* then you will have a much easier time becoming a bulimic than another person who doesn't have those innate, inherited psychological tendencies.\n\nBut let's not forget that ENVIRONMENT plays a big part. It certainly does not help that the media bombards us with images of extremely skinny people, and society pressures us to emulate them.\n\nSo if you add a high-pressure environment, plus an inherited tendecy to be a control freak, you have the perfect combination for a home-grown bulimic.

It can be either.\n\nIt most commonly exhibits familial transmission consistent with autosomal dominant (AD) inheritance (approximately 90%), but X-linked (5-10%) and much less commonly autosomal recessive (AR) or mitochondrial inheritance have been reported.

In adoption studies, psychologists studied how much children's IQ was related to their parents. For example, was the biological child's IQ closer to their parent than the adopted child to their new parent? They found that biological children have a closer IQ to their biological parents than do adopted children to their new parent. So that means that nature must have played more of an important role than nurture. However, when the adopted child came from an impoverished environment and was put in a better home with better parents, their IQ increased dramatically, which means that nurture still plays a great role in influencing a child's IQ.\n\nThe types of twins are fraternal or identical.\n\nThe nature vs. Nurture debate is about whether you become the person you are because of (nature) biological factors (meaning you are born with a certain IQ and certain characteristics that you inherited from your parents and cannot change) or because of (nurture) environmental factors such as how your parents raised you, if you were in an abusive or good home, etc.

PKU is inherited when both parents have the PKU gene and both pass it on to their baby. A parent who has the PKU gene, but not the disease, is called a "carrier."  A carrier has a normal gene as well as a PKU gene in each cell. A carrier's health is not affected in any known way.\n\nWhen both parents are carriers, there is a one-in-four (25 percent) chance that both will pass the PKU gene on to a child, causing the child to be born with the disease. There also is a two in four (50-50) chance that the baby will inherit the PKU gene from one parent and the normal gene from the other, making it a carrier like its parents. There also is a one-in-four chance that both will pass on the normal gene, and the baby will neither have the disease nor be a carrier. These chances are the same in each pregnancy.

Ok, here's how it works. It seems that you need genotypes. A homozygous trait is a trait that is both dominant and recessive. Therefore, the organism possesses the dominant trait. A heterozygous genotype is always dominant (dominant is dominant over recessive). For example, brown hair (B) is dominant over blond hair (b). a heterozygous person will be Hh, and will have brown hair even though both alleles are present.

I think you may be interested in reading an  article by a biopsychologist named Lawrence Harper. The article proposes a theory that suggests that experiences can be inherited through genetic means. The theory does not specifically address the notion of the inheritance of particular memories, but it may prove a useful avenue for pursuing your question.\n\nHere is the abstract from the article:\n\nCurrently, behavioral development is thought to result from the interplay among genetic inheritance, congenital characteristics, cultural contexts, and parental practices as they directly impact the individual. Evolutionary ecology points to another contributor,epigenetic inheritance, the transmission to offspring of parental phenotypic responses to environmental challenges—even when the young do not experience the challenges themselves. Genetic inheritance is not altered, gene expression is. Organismic pathways for such transmission\nexist. Maternal stress during the latter half of a daughter’s gestation may affect not only the daughter’s but also grand-offspring’s physical growth. The author argues that temperamental variation may be influenced in the same way. Implications for theory and research design are presented along with testable predictions.

dominance or recessiveness have nothing to do with what is selected, it only affects expression in the individual, this can be a tough concept to get, but basically if a gene is recessive it doesn't mean its better or worse than the alternative genes out there, it could be either. Recessive/dominant doesn't mean rare/common.

Very simply put, dominance and recessiveness are characteristics of genes.\n\nA dominant gene is expressed (shows up visibly in the offspring) when only one copy of the gene is present, on one chromosome from one parent. Let's say Tallness is a Dominant gene. If you have ONE tall parent, and get ONE copy of the Tall gene, you will probably be tall. If your tall parent was the son or daughter of a TALL and a SHORT person, they may only have ONE copy of that gene. If you get both SHORT chromosomes from Mom and DAD, you will NOT be tall. So you have 50 to 100 chance of being tall with a Dominant gene.\n\nNow, let's take the gene for BLUE eyes. It is recessive. You need TWO copies of this gene to get blue eyes. If Mom has blue eyes and Dad has blue eyes, and you get copies of both blue eye genes, you will have blue eyes. But if Mom has blue eyes, and Dad has brown eyes, you might end up with Brown eyes. Don't that make your blue eyes brown, so to speak.\n\nBUT..if Dad's mom had blue eyes and Dad's dad brown (your grandparents) and if Dad has one blue eye gene and one brown eye gene and has brown eyes AND if your Mom still has those blue peepers, you have a 1/4 chance of ending up with one blue eyed gene from AND a blue eyed gene from Dad and you will also have blue eyes like your Mum. Don't that make your brown eyes...blue?

I can only answer number one.\nThe possible traits can be determined.  But there's no way of know the exact traits of the offspring unless the parents have either two dominate or two recessive genes with every specif trait.  For instance, using punnett square:\n \n----d----d\nD  Dd Dd\nD  Dd Dd\n\nAll the possible genotypes are the same.\nSorry I couldn't answer your other questions!

This is really all about genetics. Each person has differing genes and inherit family traits!

I don't understand your use of the word controlled.\nIf you mean what is the relationship of recessive genes to Cystic Fibrosis?\nBecause the trait for CF is attached to a recessive gene it means that when that gene is passed on to a child it is harmless on its own.  The disease only occurs when one woman with the recessive linked gene mates with a male with the same recessive gene. Two recessives result in the disease happening in the child.\nThe two parents who only have half the material each on their genes are ''carriers'' of the disease.\nMost cystic fibrosis children are blond and blue eyed because these too are thought to be part of recessive genes.  \nIs that what you want to know?

Traits that are genetically based can be inherited either dominantly or recessively.  Traits refer to what we call a phenotype, and the specific combination of DNA leading to this phenotype we call the genotype.  As an example, let's consider a pea plant which has two descrete and separate heights: large and small.  To analyze the inheritance of plant height, you first establish small or large plants that breed true, for example, crossing a large plant with a large plant always breeds large plants.  Then, you breed true-breeding large and small plants together.  If large is dominant (and small recessive), the offspring will all be large, because the 'large' genotype is dominanting the 'small' genotype.  If small is dominant the offspring are small.  Dominant and recessive are mutually exclusive classifications of the genotype.  \n\nTo extend this analysis further, you can cross that large x small generation (called the F1 generation) together (this is called an intercross).  Let's say large is dominant and the F1 plants are all large.  Intercrossing the F1 will lead to both small and large offspring.  If only one gene is responsible for the plant height, then the ratio of large:small plants will be 3:1.  \n\nThis is the essence of genetics, the linkage of genes to discrete, measurable characteristics.  Not all characteristics are genetic, and for complex issues such as diseases many genes play a role.  But the essence is still the same.  It works because for every person or plant, you receive one genome set from your mother and one genome set from your father, thus the inheritable characteristics you develop can then be passed down to the next generation.

A simplified version would go like this:\nGenes are the entities that control inheritance.\nThe genes are located in linear order along thread-like structures called chromosomes.\nIn molecular biology, genes are the segments of DNA which cells transcribe into RNA and translate, at least in part, into proteins.  These protein (often structural materials or enzymes) determine the traits of the cells.\nThe structure of these proteins is determined by the structure of the RNA.\nThe structure of the RNA is determined by the structure of the DNA.\nThe structure of the DNA is determined by the structure of the chromosomes or genes.\nAll of these structures are molecular in nature.

Ooh those are fun to make!  A pedigree is a chart that shows a trait, and carriers for that trait.  You basically start off with a family tree form.  Start off with say your grandparents, then your parents, then your siblings and yoruself and if you have kids go down another level.  I believe guys get squares and girls get circles, and if a trait is dominant in both chromosomes, you completely fill in the circle or square, if the individual is only a carrier, but the gene is not expressed, you fill it in half way...on one side...not up or down...so left or right, and if the person isnt' a carrier you leave it blank, or white.\n\nHere's a good link of a pedigree:\n\nhttp://faculty.clintoncc.suny.edu/faculty/Michael.Gregory/files/Bio%20101/Bio%20101%20Laboratory/Pedigree%20Analysis/PEDIGREE.HTM

the result of fl is barr(if it is dominant) or else white.one main ground rule of inheritance is that it may be white or barr but one can be dominant only for 2 generations it's not the matter but in  the third gen.the recessive will take the turn
