Answer:

2 out of 4

Explanation:

Let the allele for cleft chin be represented by A, while the alternate recessive version would be a.

A parent that is heterozygous for cleft chin would have the genotype Aa.

A parent without cleft chin would have the genotype aa.

Aa x aa

Aa Aa aa aa

Aa - cleft chinned = 2/4

aa - normal chin = 2/4

Thus, two out of every four (2/4) of their offspring would have cleft chin.
