BIOL 160Use this for the following questions.
A researcher is studying the genetics of parakeets (Budgerigars, Melopsittacus
undulatus). The researcher has a true breeding population of green parakeets, and a
true breeding population of blue parakeets. The researcher designates these
populations as P1 generations, The researcher crosses those populations to produce
an F1 generation. The entire F1 generation is green. The research self-crosses the F1
generation to produce an F2 generation. Around 75% of this F2 generation is green,
and the rest are blue.

Blue and Green
3 1pt) How many genes does the above study investigate?
Just one gene.
4 2pts) How many alleles does the above study investigate? Name them. If
