In humans cleft chin is dominant to no cleft chin. Which genotype(s) would produce offsprings that does not have cleft chin? cc cc cc

## Step 1<br />In this problem, we are dealing with a genetic trait, specifically the presence or absence of a cleft chin in humans. The trait is determined by a single gene with two alleles: one for a cleft chin (C) and one for no cleft chin (c). The cleft chin allele is dominant, which means that an individual only needs one copy of this allele to have a cleft chin. <br /><br />## Step 2<br />The genotype of an individual is the combination of alleles they have. In this case, the genotype for an individual with a cleft chin could be either CC or Cc, as they would have at least one copy of the dominant allele. <br /><br />## Step 3<br />On the other hand, an individual without a cleft chin would have the genotype cc, as they would have two copies of the recessive allele. <br /><br />## Step 4<br />Therefore, the genotype that would produce offspring without a cleft chin is cc.
