what is a genotype hybrid?
142636
Genotype are the genes present in the DNA of an organism that determine that organism's traits. Each genotype is referenced with two similar letters - one capital one lower case. This means that there are three possible combinations, e.g. BB or Bb or bb. The capital letter represents the dominant gene and the lowercase the recessive gene. So each offspring gets a gene which is a combination of those passed down from its parents. By way of example, lets look at the size of your nose. Your Dad has a big nose with genotype Bb and your Mum has a small nose with genotype bb. If your Dad passes down the B and your Mum the b then you will have a big nose (Bb) because the B will dominate the b. But if they both pass down the b (bb) then you will have a small nose. If you get bb then that is called homosygous (pure) genotype and if you get Bb that is called hetrozygous (hybrid) genotype. The reason it is sometimes possible for a child to look nothing like either of their parents is that if both parents are hybrid genotypes (eg. in the nose example both are Bb and therefore both have big noses) all three combinations (BB, Bb or bb) are possible and you may get the bb and have a small nose...

Hybrid rockets combine liquid-propellant and solid-propellant technologies. Basically a hybrid is a solid-propellant rocket that contains the fuel part of a solid-propellant mixture but not the oxidizer, so it cannot burn on its own. A liquid oxidizer is injected into the forward end of the rocket and ignited to burn the solid fuel. If desired a hybrid can be designed with a variable valve in the oxidizer line for throttleability and stop/restart capability. Both model rocketeers and inductry have shown interest in hybrids. See the ref.

I do not think you could hybridize a turkey and a chicken. They are too far apart in species variation. A chicken has 78 chromosomes, but I do not know the turkey number. I think we would have seen the hybrid, by now, if it were possible.

Well if they ensure that the mate a homozygous dominant with a homozygous recessive (eg B/B x b/b, as is the case in monohybrid crosses, you can make sure the parents have this genetics by watching them over generations, mating only dominant with dominant and recessive with recessive) then you'd know that for a diploid plant/animal, as all offspring get one gene from one parent and one from the other, all of the F1 would have to be B/b - so heterozygous for that trait. So they'd all be the same genetically for that particular trait! But then if you crossed the F1 with one-another they wouldn't all be the same... crossing heterozygotes youd get some B/B, some B/b and some b/b...

Recombination (I presume this is what you're talking about) can do both. It creates new combinations of alleles at different gene loci that might be especially advantageous in a particular environment. The down side is that it can separate them also, so a parent that has a good combination will produce some offspring that don't have the combination because recombination has separated them in the gametes.\n\nI hope this is what you were asking about.

You are quite correct. This isn't a ground breaking observation or anything, although you did well to think of it on your own.\n\nThis is one of the major problems with hybrid animals and plants because the F1 generation is usually relatively uniform while the F2 generation can produce throwbacks to either or both grandparents. \n\nBecause the chromosomes are randomly assorted it is quite possible to produce an individual that contains little or even no genetic material from one or even two grandparents.

Hybridisation (Commonwealth English) or hybridization (American English) is the mixing of atomic orbitals belonging to a same electron shell to form new orbitals suitable for the qualitative description of atomic bonding properties. Hybridized orbitals are very useful for rationalizing in hand waving discussions the shape of molecular orbitals for molecules made of atoms of the groups 2,3,4 of the periodic families of elements. On the other hand, groups 1,5,6 and 7 in the periodic table do not hybridise, i.e. this approach is in that case not useful. Hybridisation is an integral part of the valence shell electron-pair repulsion (VSEPR) theory.\n\nAcid: acid is a molecule or ion that is able to give up a proton (H+ ion) to a base, or accept an unshared pair of electrons from a base. An acid reacts with a base in a neutralization reaction to form a salt.\n\nBase:Base is a chemical compound that absorbs hydronium ions when dissolved in water (a proton acceptor).\n\nSalt:Salt is a term used for ionic compounds composed of positively charged cations and negatively charged anions, so that the product is neutral and without a net charge. These ions can be inorganic (Cl-) as well as organic (CH3-COO-) and monoatomic (F-) as well as polyatomic ions (SO42-).\n\nFor further queries email me:trust_amplifier@yahoo.com

Actually, if you count the varieties within each species, you'll find that there are hundreds and hundreds.  For instance, there are several hundred known cultivars of watermelon alone.\n\nA cultivar is a "cultivated variety".  Most of them are hybrids.  Ninety percent of that you find in a local grocery store is going to be a hybrid of one kind or another.\n\nHorticulturally speaking, melons are called cucurbits, by the way.

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.

EEEEH. I'm not really good with this mumbojumbo stuff but here is a site on genotypes and stuff. -> http://janis7hepc.com/Genotypes.htm <-

gene I think is what you are looking for. Not sure the question makes sence.

A genotype is the actual genetic code of an organism, the sequence of the base pairs on the DNA. The phenotype is what those genes actually express, what you would see if you looked at the organism.\n\nSay there's a gene that controls the color of a mouse's fur. We'll call the dominant form of the gene which gives brown fur, B. The recessive form, for white fur, will be b.\n\nA mouse gets one copy of the gene (called an allele) from each parent, for a total of two. That means there are three combinations of alleles: BB, bb, and Bb. A mouse with two recessive alleles will be white, and a mouse with two dominant alleles will be brown. A heterozygous mouse (with one dominant and one recessive copy) will also be brown.\n\nGenotype          Phenotype\nbb                White\nBB                Brown\nBb                Brown\n\nSo even though the BB and Bb mice have different genotypes, they have the same phenotype.\n\nIn the example above, the phenotypic ratio would reflect the amount of mice of a different color in a population. For example, if you crossed two heterozygous mice, the brown to white ratio of the offspring would be 3:1. The genotypic ratio, reflecting the genetic code of the offspring (BB to Bb to bb), would be 1:2:1.

Punnett squares are really important in genetics. They allow for determining possible genotypes and phenotypes if the genotype of parents is known you can predict the possible genotype of offspring. \nFor example if you cross a homozygous dominant tall plant (TT) with a homozygous recessive short plant (tt) you would have all heterozygous tall plants:\n\n                   T          T\n           t       Tt         Tt\n           t       Tt         Tt\n\nIf you crossed two heterozygous plants for tall (Tt) you would have 1/4 homozygous tall, 1/2 heterozygous, 1/4 homozygous short.\n\n                   T             t\n         T        TT          Tt\n         t          Tt           Tt\n\nHope that helps.
