Dihybrid Crosses

In the cross shown, which of the following most likely represents the genotypes of the parents?

Two black guinea pigs are both heterozygous for hair length and hair color (BbHh). How many of their offspring will have short, white hair?

A tall, purple flowered pea plant (TtPp) is crossed with one that is short (tt) and has purple flowers (Pp). How many of their offspring will be short and have white flowers?

In fruit flies, vestigial wings are recessive (gg), and sepia eyes (ee) are also recessive. A red eyed, vestigial winged fly (Eegg) is crossed with one that is red eyed and has normal wings (EeGG). How many offspring will have sepia eyes and normal wings?

A fruit fly with sepia eyes and vestigial wings (eegg) is crossed with one that is heterozygous for both traits. How many of their offspring will have sepia eyes and normal wings?
