Answer:

There will be no children without dimple and have only children with dimples.

Step-by-step explanation:

Dimples in humans are characteristic that is influenced by the dominant allele of a gene which is represented by D and its recessive allele is d. So the DD which is pure and Dd which is a heterozygous condition for this characteristic and represents offspring or individual with the dimples. The pure condition of recessive alleles dd represents an individual without dimples.

Dd crosses with DD:

gametes will be D and d, and D and D.

D d

D DD Dd

D DD Dd

There are only two types of genotypes are produced that are:

DD - individual with dimples

Dd - individual with dimples

Thus, there will be no children without dimple and have only children with dimples.
