What is the phenotypic ratio for the following cross. Assume

that the principle of dominance applies, and the organisms in

question are diploid and sexually reproducing. The organisms

(fruit flies in the genus Melanogaster (male and female) are

heterozygous for three traits: AaBbCc. Dominant “A” is for

brown coloring; recessive “a” is for gold coloration; dominant

“B” is for red eyes; recessive”b” is for white eyes; and,

dominant “C” is for 4 wings, and recessive “c” is for no wings

(wingless). Use a Punnet square to supply the possible

phenotypes. 

For fun (and some bonus points), what are the possible gametes

produced by an organism that is heterozygous for these five(5)

traits, AaBbCcDdEe? You DO NOT have to do the Punnett

square, just list what would go on one axis
