Unformatted text preview: upper bands Marker F: Columbia upper bands 2. (2 points) At a given locus, two alleles, 1 and 2, are present in a population in Hardy-Weinberg equilibrium and no other alleles are present at appreciable frequencies. Homozygotes for allele 1 represent 36% of the population. What fraction is heterozygous? 3. (2 points) Two wild-type alleles, 1 and 2, are present in a population in Hardy-Weinberg equilibrium and together make up 90% of the allele frequency at that locus. Homozygotes for allele 1 represent 9% of the population. What fraction of the population is homozygous for allele 2? 4. (2 points) In a population of 1 million people, 100 albinos (homozygous recessives, aa) were found. How many normal (homozygous dominants, AA ) individuals will be found in the next generation under Hardy-Weinberg equilibrium (assume that the population is still 1 million)?...
