(Problem 66a) Male house cats are either black or orange; females are black, orange, or calico. If these coat-color phenotypes are governed by a sex-linked gene, how can these observations be explained? A.The gene is on the X chromosome and three alleles must be involved. B.Calico males die before birth C.In males, orange is always dominant over calico. D. The gene is on the X chromosome and heterozygous females display the calico phenotype. . E.Calico males are sterile. (Problem 66...

If there is a female calico cat (genotype Xºxº), where the Xº confers orange-colored fur and the Xº confers black fur. If in all the cells in a patch of color on the left paw, the chromosome with the Xº allele is condensed into a Barr body, what color is the fur in the patch on that paw? Select one or more: a. white b. orange c. black d. calico (a mix of orange and black)
In cats with tortoiseshell coat color, the fur is white with patchy black and orange spots....
In cats with tortoiseshell coat color, the fur is white with patchy black and orange spots. In cats, the tortoiseshell gene is on the X chromosome, and the tortoiseshell phenotype requires the presence of 2 different alleles at this locus: one for orange fur (o) and one for black fur (b). What phenomenon best explains why female cats can inherit tortoiseshell coat color? In females, the alleles for coat color are pleiotropic, resulting in patches of orange and black coat...
Question 3 20 pts Genetically, why does a Calico cat have the orange and black patterned...
Question 3 20 pts Genetically, why does a Calico cat have the orange and black patterned patches of fur? The fur pattern is due to activation of a homozygous autosomal chromosome. The fur pattern is due to activation of a heterozygous sex linked chromosome. The fur pattern is due to activation of a homozygous sex linked chromosome. The fur pattern is due to inactivation of a heterozygous sex linked chromosome The fur pattern is due to inactivation of a homozygous...

Coat color in cats is partially determined by the X-linked O locus. OO females and OY males are orange, while oo females and oY males are black. Oo females are a mosaic of orange and black (calico cats). In a population of cats where this locus is at Hardy-Weinberg equilibrium, 4% of males are orange. a) What is the frequency of the o (black) allele in the population? ____________ b) What is the expected frequency of calico cats in this population, assuming equal...

6. The world's first cloned pet, the kitten CC (a play on the words Copy Cat and Carbon Copy) was the result of a nuclear transfer experiment in which the nucleus from the diploid somatic cells of a female calico cat named Rainbow was injected into an egg (from an unnamed donor cat) whose own nucleus had been removed previously (similar to the "Three Parent Baby" experiment described in Lecture 12). The reconstituted egg was then implanted into the uterus...
