Question

In horses, black (B) is the dominant color; brown (b) is the recessive color. Consider the cross seen here, between two black horses (Bb). What is the probability that these two horses will have a foal that is brown?
A) 0%
B) 25%
C) 40%
D) 50%

Answer 1

B) 25%

reason: the possible genotypes are

BB,Bb,Bb,bb

brown colour foal means genotype bb. therefore 25%

Answer 2

25% because three will be BB , Bb and Bb resulting into black colour. One will be bb resulting in brown colour. So 25%.
