Albinism, an autosomal recessive trait characterized by an absence of skin pigmentation, is found in 1 in 4000 people in populations at equilibrium. Brachydactyly, an autosomal dominant trait producing shortened fingers and toes, is found in 1 in 6000 people in populations at equilibrium.

A. Calculate the frequency of the recessive allele at albinism locus.
B. Calculate the frequency of the dominant allele at albinism locus.
C. Calculate the frequency of heterozygotes for albinism.
D. Calculate the frequency of the dominant allele at brachydactyly locus.
E. Calculate the frequency of the recessive allele at brachydactyly locus.
F. Calculate the frequency of heterozygotes for brachydactyly.
G. What is the frequency of mating between heterozygotes for albinism?
