Gene a has two alleles (a1 and a2). a1a1 homozygotes are twice as likely to survive from birth to reproductive age as heterozygotes or a2a2 homozygotes (w11=1, w12=0.5, w22=0.5). a population starts with 40 individuals of each genotype allowed to mate at random. their progeny then survive according to the fitness values given above. what will be the allele frequencies in those progeny when they reach reproductive age
a. 0.40 a1, 0.60 a2 b. 0.50 a1, 0.50 a2 c. 0.60 a1, 0.40 a2 d. 0.80 a1, 0.20 a2 e. all a1

In fruit flies, gray bodies (g) are dominant over black bodies (g), and brown pigments (n) are dominant over yellow pigments (n). each individual possesses two alleles for each trait. if a fly that is homozygous dominant for both traits is crossed with a fly that is homozygous recessive for both traits, what is the predicted genotype of the offspring.
