Question

14 the following pedigree shows the inheritance of a trait in two generations of a family. family pedigree key □ = male ○ = female which statement describes generation iii in this family? a the children have a fifty percent chance of displaying the trait because it is dominant, and one parent in the second generation displays the trait. b none of the children will display the trait because it is recessive, and one parent in the second generation displays the trait. c the pedigree does not indicate whether the trait is dominant or recessive; therefore, an accurate prediction cannot be made. d all the children will display the trait because it is dominant, and one parent in the second generation displays the trait.

Explanation:

A pedigree chart shows the inheritance of a trait. To determine the probability of the trait in Generation III, we need to know if the trait is dominant or recessive. Since the pedigree does not indicate whether the trait is dominant or recessive, we cannot accurately predict the probability of the trait in Generation III.

Answer:

C. The pedigree does not indicate whether the trait is dominant or recessive; therefore, an accurate prediction cannot be made.
