A cleft chin is a dominant trait one parent is heterozygous for cleft chin and the other parent does not have collection what is the probability that the offspring will have a cleft chin

50% or 0.5 is the probability that the offspring will have a cleft chin.

Explanation:

Data given:

Cleft chin = dominant, genotype CC

one parent, heterozygous so genotype, Cc

other parent = no cleft chin, genotype is cc (recessive)

probability of child with cleft chin =?

The cross between the given genotype will be shown in punnet square:

     C  c

c    Cc cc

c     Cc  cc

The results obtained from the cross shows that 50% chances of the progeny having cleft chin.

The phenotype ratio: cleft chin: no cleft chin

                                                 1:1

the genotype ratio of the progeny

heterozygous dominant : recessive homozygous

1:1
