A fly has two alleles for the color of its eyes. The green allele is recessive, and
is represented by q. The blue allele is dominant, and is represented by p. If 44
of 100 organisms are green, what is p?
Homozygous dominant + Heterozygous + Homozygous recessive = 1
p+ 2pq + q*=1
O A. 0.34
OB. 0.66
O C. 0.44
O D. 0.56

answer; i believe that the correct answer is ; males are hemizygous for the x chromosome;

if you know your abc's you should be able to get your answer or just use google
