Question

Coat color in cats is determined by genes at several different loci. At one locus on the X chromosome, one allele (X*) encodes black fur, another allele (X9) encodes orange fur. Females can be black (XXx), orange (X°x9), or a mix called tortoiseshell (X xo). Males are either black (X+Y) or orange (XoY). i. Bill has a female tortoiseshell cat named Patches. One night Patches escapes and mates with an unknown male cat. Patches later gives birth to the following kittens: one orange male, one black male, two tortoiseshell females and one orange female. Give the genotypes of Patches, her kittens and the unknown male. A. B. Though very uncommon, there have been male tortoiseshell cats observed How might this be possible? Chapter 5 2.. What is the difference between epistasis and dominance? How many genetic loci a

Explanation / Answer

In this question,patches is female with genotype X+Xo.

The male with which it mated was orange with a genotype of XoY.

A cross between them will have following types of results
