gayaneshka [121]

Answer:

Probability of Dimples and a cleft chin among their offspring = 1/4

Probability of no dimples and a non-cleft chin = 1/4

Explanation:

the allele for the dimple trait D is dominant over the allele for the non-dimple trait d.

the allele for the cleft chin trait C is dominant over the allele for the non-cleft chin trait c.

Mr. Smith has heterozygous alleles for both traits.

Mrs. Smith does not have dimples, nor does she have a cleft chin

Mr Smith DdCc x. ddcc

Probability of Dimples and a cleft chin among their offspring = Dd x dd = 1/2

Cc x cc = 1/2 = 1/2*1/2 = 1/4

Probability of no dimples and a non-cleft chin = Dd x dd = 1/2, Cc x cc = 1/2 = 1/2*1/2 = 1/4.
