*worth 20 points* having dimples is a dominant trait having no dimples is recessive. a father has the genotype dd and a mother has the genotype dd. fill in the punnett square below to show their possible offspring.

See the attached image.

Explanation:

Having dimple is dominant over having no dimple.

The allele of dimple is D and the alternate form is d.

A father with Dd genotype mates with a mother with Dd genotype, the genotype and phenotype of the offspring will be:

1 DD - dimpled

2 Dd - dimpled

1 dd - no dimple

See the attached image for the punnet square result.

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project
