In humans, cleft chin is dominant to no cleft chin. Which genotype(s) would produce offsprings that does have cleft chin? cc D cc Cc

## Step 1<br />In this problem, we are dealing with a genetic trait, specifically the presence of a cleft chin in humans. The trait is determined by a single gene with two alleles: 'C' (dominant) and 'c' (recessive). The dominant allele 'C' results in a cleft chin, while the recessive allele 'c' does not.<br /><br />## Step 2<br />The genotype of an individual is the combination of alleles they possess. In this case, the genotype can be either 'CC' or 'Cc' for an individual to have a cleft chin. This is because the presence of at least one dominant allele 'C' will result in a cleft chin.<br /><br />## Step 3<br />The genotype 'cc' would not result in a cleft chin because it contains two recessive alleles. For an individual to not have a cleft chin, they must have two copies of the recessive allele, which is 'cc'.
