The expected phenotypic ratio can be determined by using the Punnett square for the given cross:
| B | B |
__________|_____|_____|
E | BE | BE |
E | BE | BE |
From this Punnett square, we can see that all of the offspring will have black fur and long ears. Therefore, the expected phenotypic ratio is:
16 Black/Long Ears : 0 Black/Short Ears : 0 White/Long Ears : 0 White/Short Ears
In rabbits, black fur (B) is dominant to white (b), and long ears (E) are dominant to short ears (e). What is the expected phenotypic ratio of the offspring of a BBee x bbEE cross if these alleles sort independently? (B.6F)
Question 15 options:
8 Black/Long Ears : 0 Black/Short Ears : 8 White/Long Ears : 0 White/Short Ears
1 Black/Long Ears : 3 Black/Short Ears : 3 White/Long Ears : 9 White/Short Ears
4 Black/Long Ears : 4 Black/Short Ears : 4 White/Long Ears : 4 White/Short Ears
16 Black/Long Ears : 0 Black/Short Ears : 0 White/Long Ears : 0 White/Short Ears
