1 answer:
Answer:
Considering the <u>whole progeny </u> (100%), there will be
25% Black male kittens, XBY 0% Calico Male kittens 25% Calico female kittens, XBXR Explanation:
<u>Available data:</u>
The gene for Calico (multicolored) cats is an x-linked trait and codominant Calico Females receive a "B" and an "R" gene, and have black and orange splotches on white coats. Their genotype is XBXR. Males can only be black or orange, but never calico. Their genotype is XBY and XRY Cross: a female calico cat with a black male
Parentals) XBXR x XBY
Gametes) XB XR XB Y
Punnett square) XB XR
XB XBXB XBXR
Y XBY XRY
F1) Among the whole progeny:
2/4 = 50% will be black (female XBXB and male XBY) 1/4 = 25% will be Calico (female XBXR) 1/4 = 25% will be Orange (male XRY) Among females:
1/2 = 50% of females will be black, XBXB 1/2 = 50% of females will be Calico, XBXR Among males:
1/2 = 50% of males will be black, XBY 1/2 = 50% of males will be orange, XRY
