We can’t see the picture :(
Maybe post another question but with the picture
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.
