A student studying a population of butterflies wanted to determine the gene frequencies for wing color. She knew that in this particular butterfly wing color is exhibited as either yellow or black and that black is dominant. She also knew that half the butterflies in this population had yellow wings and half had black wings. Which is the following hypothesis would she most likely reject?
a) there are more yellow genes than black genes
b) there are more black genes than yellow genes
c) there are twice as many yellow genes as black genes
d) there are equal numbers of black and yellow genes
e) there are three times as many yellow genes as black genes
