In cats the gene for calico (multicoloured) cats is codominant. Females (XX) that receive a B and an R gene have black and orange splotches on white coats. Makes (XY) can only be black or orange, but never calico. Here’s what calico females genotype would look like: Xb Xr If a female calico is crossed with a black male cat A) what percentage of the kittens will be black and male (XY) B) what percentage of the kittens will be calico and male (XY)

Step 1
In this scenario, the gene for coat color in cats is located on the X chromosome. The gene for black color is represented as "B" and the gene for orange color is represented as "R". Since males have only one X chromosome (XY), they can either be black (XB) or Show more…

9. In cats, the gene for calico (multicolored) cats is codominant. Females that receive a B and an R gene have black and orange splotches on white coats. Males can only be black or orange, but rarely calico. Show the cross of a female calico cat with a black male; Female, calico = XB XR Male, black = XB Y How many offspring will be: Female and calico Female and black Male and black Male and orange Male and calico 10. Show the cross of a female black cat and a male orange cat. What percentage of the kittens will be calico and female? What color will all the male cats be?

In cats, the gene for calico (multicolored) cats is codominant. Females that receive a B and an R gene have black and orange splotches on white coats = calico. Males can only be black or orange, but never calico. Female genotypes must include XX and males XY. a. Show the cross of a female calico cat with a black male.
