In rabbits, the homozygous genotype LCLC has normal legs, LCLc results in deformed legs, and LcLc results in very short legs. The genotype FBFB produces black fur, FBFb brown fur, and FbFb white fur. If a cross is made between brown rabbits with deformed legs and white rabbits with deformed legs, what percentage of the offspring would be expected to have deformed legs and white fur?

Answer #1

A cross is made between brown rabbit with deformed leg and white rabbit with deformed leg.

FBFbLCLc FbFbLCLc

Gamets : FBLC, FBLc, FbLC, FbLc ; FbLC, FbLc

The possible offspring are :

FbLC FbLc
FBLC

FBFbLCLC

Brown fur, normal legs

FBFbLCLc

Brown fur, deformed legs
FBLc

FBFbLCLc

Brown fur, deformed legs

FBFbLcLc

Brown fur, very short legs
FbLC

FbFbLCLC

White fur, normal legs

FbFbLCLc

White fur, deformed legs
FbLc

FbFbLCLc

White fur, deformed legs

FbFbLcLc

White fur, very short legs

Out of the 8 possible offspring, 2 have deformed legs and white fur.

Probability of offspring with deformed legs and white fur = 2/8 = 25%

percentage of the offspring would be expected to have deformed legs and white fur is 25% .

Simple Dominance with 2 genes A gene in cats causes them to be black (dominant) or brown (recessive).

If you did a dihybrid cross between two black haired agouti cats, what fraction of the offspring would be expected to have each phenotype? If a dihybrid black agouti cat mated with a brown cat that was heterozygous for the agouti gene, what fraction...

Remember that albinism is a recessive Mendelian trait. A rabbit breeder has one albino rabbit with the genotype "aa." He also has a brown and white-colored rabbit (pictured) with the genotype Aa (it had a single albino parent, and one brown-colored, brown-eyed parent). The breeder is wondering whether these two rabbits will produce any albino offspring, and wants to know on average how many offspring will be albino from a cross between his two rabbits? What would you tell him?...

Draw a Punnett square representing the cross between a heterozygous individual and a homozygous recessive individual for gene A. Assume that gene A is inherited in a normal Mendelian fashion and assorts independently. What are the chances that these two individuals would have offspring that are… AA? Aa? aa? What alleles are in each of the gametes (sperm & eggs) for the heterozygous individual? Now let’s practice using the “rule of and.” What are the chance of the offspring from...

1. You cross two homozygous parental pea plants. One has purple flowers and is tall, the other has white flowers and is short. All of the F1 plants are purple and short. What are the genotypes of the parents and the F1? If you were to cross the F1 generation, what genotypic and phenotypic ratio would you expect to see in the offspring?
