In mice, an allele for apricot (a) eyes is recessive to an allele for brown (A) eyes. At an independently assorting locus, an allele for tan (t) coat color is recessive to an allele for black (T) coat color. A mouse that is homozygous for brown eyes and black coat color is crossed with a mouse having apricot eyes and a tan coat. The resulting F1 are intercrossed to produce the F2. What is the probability of an F2 mouse having a black coat and apricot eyes?

1) Coat color in mice is determined by several independently assorting autosomal genes. Gene A is involved in the distribution of pigment along the hair. A dominant allele (A) produces a hair color called "agouti"--the hair has dark pigment at the base and tip of each hair shaft and yellow pigment in the central portion of the shaft. Homozygous recessive mice (aa) are missing the yellow stripe and thus have solid dark-colored hair. Gene B is involved in the color...

in guinea pigs, the allele for black coat is (B) is dominant over the allele for a white coat (b). at an independently assorting locus, an allele for rough coat (R) is dominant over the allele for smooth coat (r). a guinea pig that is homozygous for black color and rough coat is crossed with a guinea pig with a white, smooth coat. in a fears of matings, the F1 are crossed with guinea pigs having a white, smooth coat....

In mice, short tails (l) are recessive to long tails (L), and tan coat color (b) is recessive to black (B). An LLbb mouse is bred to an llBB mouse. a.What are the expected phenotypic ratios in the F1 generation? b.If two of the F1 progeny are bred, what are the predicted phenotypic ratios in the F2 progeny?

In guinea pig, white coat (f) is recessive to black coat (F) and curly hair (h) is recessive to straight hair (H). A breeder crosses a guinea pig that is homozygous for white coat and curly hair with a guinea pig that is black with straight hair. The F1 are then crossed with guinea pig having white coat and curly hair in a series of testcrosses. The following progeny are produce from these testcrosses: white, curly 31 white, straight 12...

1.My wife has black color eyes, the dominant trait. All of her family and relatives have dark eyes too. I have light color eyes (blue), the recessive trait. We are hoping for a blue-eyed baby. What is the probability we will have a baby with blue eyes? What is the probability we will have a baby with dark eyes? 2. In humans, tongue rolling is a dominant trait, those with the recessive condition cannot roll their tongues. Bob can roll...

In the snail Cepaea nemoralis, an autosomal allele causing a banded shell (B ) is recessive to the allele for unbanded shell (O ). Genes at a different locus determine the background color of the shell; here, yellow (Y ) is recessive to brown (Bw ). A banded, yellow snail is crossed with a homozygous brown, unbanded snail. The F1 are then crossed with banded, yellow snails (a testcross). What will be the phenotypic classes resulting from a testcross if...

I answered part a, not sure if its correct tho. I need someone to look it over and tell me if it's correct and answer part b. The agouti locus in mice has three alleles: a is recessive and confers a black coat, A is dominant to a and confers an agouti coat, and AY is dominant to both and confers a yellow coat. AY is also a recessive lethal. In addition, the independently assorting c allele is recessive (to...
