The genotype is [tex]X^BX^b : X^bX^b : X^BY : X^bY[/tex] ( 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 [tex]X^BX^b : X^bX^b : X^BY : X^bY[/tex] ( Calico : Black : Black : orange )
The phenotype is 1 : 2 : 1 ( Calico : Black : orange )
Answer:
Whether calico, tortoiseshell, orange, black, brown, or gray, a cat’s fur color is derived from two dominant colors: Black and red. These colors can mutate into different shades—black can become chocolate, cinnamon, lilac, blue and fawn.
