An autosomal locus has alleles A and a.
The allele frequencies in a population at Hardy Weinberg equilibrium are
p = Freq(A) = 0.5
q = Freq(a) = 0.5
What is the frequency of homozygous wild-type (AA) in this population?
Enter a single number between 0 and 1, for example, 0.33
In a large, randomly mating human population, the frequencies of the IA, IB, and i alleles are 0.7, 0.2, and 0.1, respectively. Calculate the expected frequencies for each blood type. (show solution)
Three linked loci A, B, C (each with two alleles) in
a random mating population have the gametic
frequencies as shown below. Calculate the
linkage disequilibrium D / Dmax between each
pair of loci. Explain why the results seem
