Problem: Anthropology 1 Genetics Problems Hardy-Weinberg
Q1. Why does the Hardy Weinberg model only work for calculating the frequencies of genes in a breeding population as long as there is a large size, equal males and females of breeding age, random mating, and the absence of mutation, natural selection, gene flow and genetic drift?
Q2. The Hardy-Weinberg model states that if a population is in equilibrium you can predict the genotype and phenotype distribution for a characteristic, even if only one of the gene frequencies is known. What are the gene (allele) frequencies in this population if there are 50 people in a population and two of them are albinos, exhibiting a rare recessive gene. (A = normal, a = albino)
Q3. In a make-believe population there are two co-dominant genes for eye color, R and B (red and blue) the gene frequency for R is .5. What is the gene frequency for B? What is the expected genotype and phenotype frequency if the population is in equilibrium? Need Assignment Help?
Q4. In a population, 16% of the population has blue eyes, 84% has brown eyes. Although eye color is polygenic, let us assume for this problem that the brown- eye allele is dominant over the blue-eye allele and that the population is in Hardy-Weinberg equilibrium. What are the allele frequencies? What are the genotype frequencies?
