what will be the phenotype of any F1 offspring produced from this marrige?

Let's assume that "tongue rolling" is a dominant trait (I believe it is), and that it is not sex-linked. Let's call the dominant allele "R" and the recessive allele "r". The female must be rr, because the heterozygous condition, Rr, will yield a person who is able to roll her tongue.\n\nAll offspring will be able to roll their tongues.\n\nHere is the cross:\n\n-----R----R----\nr | Rr -- Rr\n\nr | Rr -- Rr\n\nAs you can see, all F1 offspring will be heterozygous, and will therefore all be able to roll their tongues.\n\nBy the way, Grumpykiwi, it doesn't mean that it isn't dominant. It merely means that your mother was HETEROZYGOUS, rather than homozygous dominant, as was the man in the problem.

Ss and Ss\n\nGenotype of both parents are heterozygous. If you draw out the Punnet square, you see 1/4 of the offspring will have long hair while 3/4 will have short hair. The phenotypic ratio of long hair to short hair ends up being 1:3, just like the puppies are 2:6.\n\nGenotype ratio ends up being:\n1/2 heterozygous Ss\n1/4 homozygous dominant SS\n1/4 homozygous recessive ss\n\nHope this helps.

Possible offspring will have a better gene base?\n\nI don't know, but I'm attracted to females of other races more than my own.

Trihybrid cross, 27:9:9:9:3:3:3:1 phenotypic ratio\nbut what are the recessive traits

It has autosomal dominant inheritance pattern.  So, assuming your spouse does not have neurofibromatosis and is recessive (aa), and you are either homozygous or heterozygous (AA or Aa).  Your child has a 100% chance of receiving it if you are homozygous and a 50% chance of receiving it if you are heterozygous.

Husband- Heterozygous since there are albino children.\nWife- Homozygous Recessive because it's the only way the recessive can show up.\nPigmented Children- Heterzygous since the dominant trait showed up but the other parent was homozygous recessive.\nAlbino Children- Homozygous Recessive for the same reasons as the mother.

A, they will have the same phenotype, but not necessarily the same phenotype.  If you are basing this question on simpler Mendelian genetics you could have both parents with trait A, resulting from Aa (parent 1) and Aa (parent 2), but the offspring genotype is AA.  They all appear the same, but they aren't on the genetic level.

very simple\n\nBecause sexual reproduction involves 2 species(man and woman) which entails 2 different genetic make-up. Therefore,\nthe offspring that will be produced will be based from the resulting gene of the mother and the father\n\nwhile asexual reproduction do not involve a 2nd party and so naturally it will produce another organism which is identical since it is organically within its genetic make-up

This is about as close as I can get you. Good luck\nhttp://www.genetree.com/product/dna-test-collection.asp

The offspring of two humans is human. Until scientists declare that there is a homo superior intead of a homo sapien based on chromosome differences, there can be no other result.

You would get two different genotypes and phenotypes.\nIf you were crossing a tall, heterozygous plant, Tt with a short plant, tt, you would get 50% Tt and 50% tt.

Let's take the Blue eyes - brown eyes example.  Brown is the dominant trait, so we'll use the capital B letter.  Blue is the recessive trait, so we'll use the b letter.  A person with blue eyes has the genotype bb (got a b from dad and a b from mom).  A person with brown eyes can be homozygous BB (got B from dad and B from mom) or heterozygous Bb (got B from one parent and b from the other parent).\nA first generation usually starts with pure breeds, so both homozygous.  We'll have BB and bb as the starting parents.  Those parents produce gametes in their gonads.  Let's say that mom has blue eyes and dad has brown eyes.  All her eggs will have the b gene as all dad's spermatozoids will have the B gene.  If you want to make the Punnett square, you'll find that all babies will have 100% probability to be Bb\n____|__B__|__B__\n__b_|_Bb__|_Bb__\n__b_|_Bb__|_Bb__\nThe second generation is made by taking two of those offspring and crossing them.  First, you have to find out what alleles will be in the gametes.  Half of the eggs will be b and half will be B.  Also, half of the spermatozoids will be B and half will be b.  In the Punnett square you'll have.\n____|__B__|__b__\n__B_|_BB_|_Bb_\n__b_|_Bb__|_bb__\nHere, the babies will have 25% chance to have blue eyes (bb) and 75% chance to have brown eyes (25% homozygotous BB and 50% heterozygotous Bb).

1/2\n\nFather = bb (as blue eyed)\nMother = Bb ( as her father was blue eyed, must have one b allele)\n\ntherefore,1/2 the children will be Bb (brown eyed) and half bb  (blue eyed)

The genotype is determined by the exact genes received from the individual's parents.\n\nThe phenotype is what "shows up", or expressed, and that is determined by which of the genes received from the individuals parents are dominant, codominant, or recessive.

Not possible. Genetics give you what you have, be thankful for it.

If it is inhereted then you need to go see a genetic counsseler. They will trace your family pedegree for the trait and find out if it is dominant or reccesive and the likelyhood of passing it on. But as a fair warning if it is somewhat rare and the effects show in you then it is probably reccesive so you have a 100% chance of passing it on. However if it is reccesive and your partener does not pass it on then it wont effect your kids :) ...\n\nsorry if you already know this, my point is you should se a genetic counseler. They will tell you everything you need to know.
