Question

Two bunnies are ready to mate. A large, fluffy tail is the dominant trait (F). A small tail is recessive (f). If both bunnies are heterozygous for the tail trait, what percentage of their offspring could have small tails?

a) 0%
b) 25%
c) 50%
d) 100%

Answer 1

If both bunnies are heterozygous for the tail trait, there is a 25% chance of their offspring having small tails (ff genotype).

Step-by-step explanation:

In this scenario, both bunnies are heterozygous for the tail trait, meaning they have one dominant allele (F) and one recessive allele (f) for tail length. When these bunnies mate, there is a 25% probability of the offspring having small tails (ff genotype), as the recessive trait is only expressed when both alleles inherited by the offspring are recessive.

Example:

• Bunny 1: Ff
• Bunny 2: Ff
• Possible Offspring:
• - 25% chance: ff (small tail)
• - 75% chance: Ff (large tail)
