If the Hardy-Weinberg equation enables us to use information on genotype and allele frequencies to predict the genotype frequencies of the next generation. In a population of 100,000 people carrying the recessive allele a for albinism, there are: 100 aa albinos and 1800 Aa heterozygous carriers.
What is a frequency of heterozygous carriers in the next generation?
Calculate the frequency for the A allele and a allele.
How this will chance the frequency of alleles in a population for the following generation?
In a population at genetic equilibrium, the frequency of the dominant phenotype is 0.96. What are the frequencies of the dominant (A) and recessive (a) alleles, and what are the expected frequencies of the AA, Aa, and aa genotypes?
For a gene existing in two alleles, what are the allele frequencies when the heterozygote frequency is at its maximum value, assuming Hardy-Weinberg equilibrium? What if there are three alleles?
