Fur color is a codominant sex- linked trait in cats. What will be the genotypes and phenotypes of a male black cat and a female calico (black and orange) cat?

The genotype is   ( Calico : Black : Black : orange )

The phenotype is 1 : 2 : 1 ( Calico : Black : orange )

Explanation:

Fur color is a co-dominant sex linked trait in cats.

The gene for fur color is present in the X-chromosome.

Males have 1 X chromosome and thus, they will have only 1 allele for the fur colour.

Females have 2 X chromosome and thus, they will have 2 alleles for the fur colour.

Considering, Orange fur color being the dominant trait and black color be the recessive one.

Male black cat = XᵇY

Female Calico cat = XBXᵇ

The cross performed is shown in the table attached:

According to the cross:

The genotype is   ( Calico : Black : Black : orange )

The phenotype is 1 : 2 : 1 ( Calico : Black : orange )
