Using the HardyWeinberg Law in Human Genetics In a given population, the frequencies of the four phenotypic classes of the ABO blood groups are found to be A = 0.33, B = 0.33, AB = 0.18, and i = 0.16. What is the frequency of the i allele?
Once upon a time there was a population of hippies living in an isolated commune called Gone. They had been there for generations, and all members were homozygous for a gene that gave them a preference for crafting necklaces out of green beads, so that every individual had the genotype GG at this locus. In another isolated commune, called Yonder, was a population of hippies that had a genetic propensity for making necklaces out of yellow beads, and everyone was homozygous for a different allele at the same genetic locus; their genotype was YY. Last year (prior to our current social isolating) everyone repaired their VW buses, and a giant gathering in celebration of the 50th anniversary was held at the Oregon Country Fair. The next few questions will ask you about these two populations that came together at the fair.
In a diploid population of A1A1, A1A2, A2A2, the A-locus was initially in H-W equilibrium. Due to certain changes in the mate choice pattern, heterozygotes completely stopped mating with each other (i.e., there is no A1A2 - A1A2 mating). Initial allele frequency of A1 was 0.3. Calculate allele frequencies and genotype frequencies in the next two generations. Comment on the further trajectory of the A-locus. [consider the population to follow a discrete generation cycle, just like the standard model of one locus population]
