Question

If you cross a red eyed male with a white eyed female, all the sons would be ___________ and all the daughters would be ______________

(a) Red eyed, red eyed

(b) Red eyed, white eyed

(d) White eyed, red eyed

I have been asked this question in an internship interview.

The doubt is from Multiple Alleles in section Extension and Deviation from Mendelian Genetic Principles of Cytogenetics

Answer 1

Correct choice is (d) White eyed, red eyed

To elaborate: he F1 daughters would be heterozygous as they get the red allele from mother and white from father- producing red eyes. The sons would have only eye colour allele from mother that would give white eye colour.
