1. If the frequency of the c allele is .15, how many individuals will be homozygous for that allele in a population of 4,550?
2. The frequency of the A allele is 0.6 in a population of 180 individuals.  How many individuals will have the a "allele" in their genome?
3. The frequency of the A allele in a population is 0.85.  How many people represent each of the 3 genotypes in a population of 100 individuals?
4. A population has been genotyped and it was found that 1137 individuals had the AA genotype, 120 individuals had the Aa genotype and 3 individuals had the aa genotype.  What is the frequency of the two alleles?
