Question

Assuming that fur colour of an animal is dark, range of colour shade and white. A cross is made between a male (AABBCC) with dark fur colour and a female (aabbcc) with white fur colour. What would be the fur colour of F_1 generation?

Accepted Answer

Correct answer: D. (d) This is an example of polygenic (quantitative) inheritance, where several genes have an additive effect on fur colour. Cross: AABBCC (dark) × aabbcc (white) All F_1 offspring = AaBbCc. Since the F_1 has an intermediate number of dominant alleles, it shows an intermediate fur colour, not the darkest or the lightest.
