5. In rabbits, C = agouti coat color, cch = chinchilla, ch = Himalayan, and c = albino. The agouti C is dominant to the three other alleles, c is recessive to all three other alleles, and chinchilla is dominant to Himalayan. Determine the phenotypes of progeny from the following crosses:
a. C ch x C c
b. cch ch x ch c
c. C ch x C cch
Homework Answers
a) Cch * Cc
| C | ch | |
| C | CC (agouti) | Cch (agouti) |
| c | Cc (agouti) | chc (Himalayan) |
possible genotypes and phenotypes are given in the punnet square.
b) cch ch * ch c
| cch | ch | |
| ch | cchch ( chinchilla) | chch ( Himalayan) |
| c | cchc ( chinchilla) | chc (Himalayan) |
possible genotypes and phenotypes are given in the punnet square.
c) C ch x C cch
| C | ch | |
| C | CC ( agouti) | Cch (agouti) |
| cch | Ccch (agouti) | cchch ( chinchilla) |
possible genotypes and phenotypes are given in the punnet square.

31. In rabbits, an allelic series helps to determine coat color: C (full color), cch (chinchilla, gray color), ch (Himalayan, white with black extremities), and c (albino, all white). The C allele is dominant over all others, cch is dominant over ch and c, ch is dominant over c, and c is recessive to all the other alleles. This dominance hierarchy can be summarized as C >ch >c"> c. The rabbits in the list on the following page are crossed...

Clownfish exhibit three phenotypeni red, yellow, and orange. If a red clownfish is mated with a yellow clownfish, the resulting progeny are all orange. a. What type of inheritance pattern do you suspect? incomplete dominance b. Construct a Punnett square to illustrate a cross between two RRRR orange clownfish.

Calculate the theoretical probability of this cross producing each of the following phenotypes shown below. Record your answer as a full percentage for each phenotype as shown in the following order. Full colour: chinchilla: light grey: Himalayan: albino * Multiple alleles control the coat colour of rabbits. • The dominant allele, produces grey colour. • The...

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...

1. At least 3 independently assorting loci are known to govern coat color in mice. The genotype C- will allow pigment to be produced by 2 other genes. The cc genotype does not allow pigment production resulting in albino mice. The striped “agouti” hair pattern depends on the genotype A- and the aa genotype is nonagouti. Finally, the color of the pigment may be black (B-) or brown (bb). Five different coat colors may be produced by the action of...

4. In mice, the Ayallele of agouti is dominant for yellow coat color but is homozygous lethal. A yellow mouse, Ay/A, that is also heterozygous for the albino allele, C/c, is crossed to an albino mouse that is also heterozygous for the Ayallele, Ay/A. c/c. What phenotypic ratios do you expect in the progeny? (True or False) a. if these genes are unlinked: 3/8 yellow, 1/8 agouti, 1/2 albino b. if these genes are unlinked: 1/3 yellow, 1/6 agouti, 1/2...

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...

7. In mice the coat color called agouti results from a dominant allele A. Mice that are AA or Aa have agouti fur. Mice that are aa have black fur. However to get any coat color at all, at least one copy of a second dominant allele C of a different locus must be present. If a mouse has genotype cc, the mouse is albino regardless of what is happening at the other gene pair. Suppose two mice with genotypes...
