In cats, black fur color is caused by an x-linked allele; the other allele at this locus causes orange color. the heterozygote is tortoiseshell. what kinds of offspring would you expect from the cross of a black female and an orange male?
a. black females; orange males
b. orange females; black males
c. orange females; orange males
d. tortoiseshell females; black males
e. tortoiseshell females; tortoiseshell males

Tortoiseshell females; black males are the kinds of offspring that I would expect from the cross of a black female and an orange male.

Explanation:

In the above question the cats of black for is caused by an allele which is linked in x. Also, we get to know that the zygote is heterozygote and it is of tortoise cell. The offspring contains the father of tortoise shell in females because of the xx zygote and the main contains black for because of the xy zygote.

It is known as dominance of the traits over the recessive traits. It also occurs in all the human beings and animals. The trait which is dominant is shown in the offspring and the trait which is recessive gets hidden. It can also be calculated through Punnett square.
