4. Genotype 

5. Phenotype

Answer 1

For this you would just want to make 2 separate Punnett squares, 1 for dimples and 1 for freckles. For Dimples, you have the father who is heterozygous (Dd) and the mother who is recessive (dd). Thus, the offspring will be 50% heterozygous with dimples (Dd) and 50% recessive with no dimples (dd). No child will be homozygous dominant.

Freckles will be the same outcome since, again, you have 1 parent heterozygous for the trait and 1 who is completely recessive.
