Can someone help me?

In fruit flies, gray bodies (g) are dominant over black bodies (g), and brown pigments (n) are dominant over yellow pigments (n). each individual possesses two alleles for each trait. if a fly that is homozygous dominant for both traits is crossed with a fly that is homozygous recessive for both traits, what is the predicted genotype of the offspring.

In the family tree below, people with the recessive trait of attached earlobes are shaded gray.

How many copies of each chromosomes should be present in each of the 4 final haploid versions of gamete?
