In a population of dogs, the allele for curly hair is dominant over the allele for
straight hair. If two parents are heterozygous for this trait, what percentage of
their offspring is expected to have straight hair?
A. 0%
B. 25%
C. 75%
D. 100 %

B. 25%

Explanation: From the information provided, Curly hair is dominant over straight hair.

Let C represent the allele for curly hair and c represent the allele for straight hair. Two parents that are homozygous for the trait will have a genotype of Cc. Therefore, a cross between them will produce 1 CC, 2 Cc and 1cc. Since straight hair (c) is recessive it must occur in a homozygous state in order to manifest outwardly. Therefore the percentage of offsprings with straight hair is 1/4 x 100 =25%
