In Drosophila, the gray body color B dominates over the black color b. What types of gametes do flies form homozygous dominant, gettrozygous, homozygous recessive?

According to the notation introduced in the problem statement, homozygous dominant flies will be written as BB. They will produce the same type of germ cells – B.

Drosophila – heterozygotes will be recorded as Bb, the germ cells they produce are of two types – b and B.

Homozygous recessive flies will be recorded as bb. Such fruit flies produce one type of germ cells – b.
