Question

In rabbits, black fur (B) is dominant to white (b), and long ears (E) are dominant toshort ears (e). What is the expected phenotypic ratio of the offspring ofa BBee x bbEE cross if these alleles sort independently?

Answer 1

Answer:

16 Black/Long Ears : 0 Black/Short Ears : 0 White/Long Ears : 0 White/ShortEars

Explanation:

Black fur (B) is dominant over white (b) and long ears (E) is dominant over short ears (e).

BBee was crossed with bbEE:

   BBee    x    bbEE (See the attached image for the Punnet's square)

Offspring:              

16 BbEe - Black fur and Long ears

All other phenotypes are 0.

Hence, the answer would be 16 Black/Long Ears : 0 Black/Short Ears : 0 White/Long Ears : 0 White/ShortEars.
