In fruit flies, long wings (w) are dominant over short wings (w), and brown pigments (n) are dominant over yellow pigments (n). each individual possesses two alleles for each trait.
1. 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?

WwNn

Explanation:

A fly that is homozygous dominant for both traits (WWNN) is crossed with a fly that is homozygous recessive for both traits (wwnn).

All gametes produced by the WWNN individual will be WN, and all gametes produced by the homozygous recessive individual will be wn.

When the gametes from the two parents combine, the zygote will be heterozygous for both genes, with the genotype WwNn.
