    1500 people were genotyped at two loci, G and H. Each locus had two alleles (G/g and H/h). The results were (frequency given for each two-locus genotype):

    Two-locus genotype Frequency
    GGHH 0.1020
    GgHH 0.1341
    ggHH 0.0441
    GGHh 0.1209
    GgHh 0.2592
    ggHh 0.1182
    GGhh 0.0358
    Gghh 0.1065
    gghh 0.0790

    What is the number of observed GH, Gh, gH, and gh haplotypes given that the GgHh genotype class contained 270 haplotypes? What are the haplotype frequencies and the allele freqencies?

    How I have started the equation:
    I first calculated the number of people with each two locus genotype. I did this multiplying each frequency by the total number of people (1500). Therefore, the total number of people with two locus genotype GGHH is .1020*1500=153 and so on.

    Our teacher provided us with a practice problem to guide us. The only difference is that in this problem, there are two locuses. I have attached this practice problem solution for addition help.

    I appreciate any help!
