Chapter 22, Problem 12PDQ

If the initial allele frequencies are p = 0.5 and q = 0.5 and allele a is a lethal recessive, what will be the frequencies after 1, 5, 10, 25, 100, and 1000 generations?

In a population of 200 people, an allele F has a frequency of 84%. What is the frequency of allele f? Using the Hardy-Weinberg equation, estimate the numbers of homozygous dominant, heterozygous, and homozygous recessive genotypes. (Remember that the formula is: p2 + 2pq + q2 = 1, where p represents the dominant allele and q represents the recessive allele.) *Be sure to account for all 200 people in the population.
If the initial allele frequencies are p = 0.5 and q = 0.5 and allele a is a lethal recessive, what will be the frequencies after one generation?
You are studying a population of penguins in Antarctica. Your DNA analysis of this population reveals that for the feather color pattern gene, 35 individuals are homozygous dominant, 35 individuals are heterozygous, and 30 individuals are homozygous recessive. After observing this population for several years, you repeat your DNA study and find that the current generation of penguins has 15 individuals that are homozygous dominant, 10 individuals that are heterozygous, and 75 individuals that are homozygous recessive. Which of the following hypotheses for this data would be supported by this data based on your understanding of Hardy-Weinberg equilibrium? This population of penguins is maintaining Hardy-Weinberg equilibrium due to its large population size. The penguins are randomly choosing mates, which has led to Hardy-Weinberg equilibrium. The penguins are very isolated, which is preventing gene flow from affecting Hardy-Weinberg equilibrium. The recessive phenotype in…
