- Assume a Hardy-Weinberg distribution for the recessive condition tercho If 9/16 of the population are homozygous dominant then what fraction have tercho? Give three digits past the decimal point.In a wright fisher population, with population of 99 only has AA individuals. However, in a one generation, someone with aa genotype migrated into the population making the new population having 100 individuals who are diploid. What is the probability that the small a allele will be fixed in the population? Show all workingsApplying the Hardy-Weinberg equilibrium. 81% of the individuals are homozygous for a recessive allele. What percentage of the individuals would be expected to be heterozygous for this locus in the next generation?
- Consider a rare deleterious recessive allele for a specific gene/locus. In this hypothetical population, the deleterious recessive allele exists at a proportion of 0.01. In an offspring with randomly chosen parents, what is the probability that the offspring will be homozygous for the deleterious recessive allele [q]?In a given population, 1 out of 400 individuals has cancer caused by a recessive allele g. Assuming the population is in Hardy-Weinberg equilibrium, what is the expected proportion of individuals who are carriers?IN a Hardy-Weinberg equilibrium, as the frequencies of homozygous genotypes increase, the frequency of the heterozygous genotype _____
- Suppose in a certain population there are 100 individuals homozygous for the A1 allele, 400 individuals homozygous for the A2 allele, and 500 heterozygous individuals. What are the genotype frequencies? What are the allele frequencies?Assume that in a Hardy-Weinberg population, 9% of the individuals are of the homozygous Tecessive phenotyne. What percentage of the individuals would be expected to be heterozygous? What percentage homozygous dominent?If 80% of a population has a heterozygous phenotype, and 16% of that population shows arecessive phenotype, is that population in Hardy-Weinberg equilibrium? In other words, doesthe population obey the rules of H-W? Perform a statistical analysis to determine your finalanswer.
- In a population of a beetle species, you notice that thereis a 3:1 ratio of shiny to dull wing covers. Does this ratioprove that the shiny allele is dominant? (Assume thatthe two states are caused by two alleles of one gene.) Ifnot, what does it prove? How would you elucidate thesituation?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?In a population that meets the Hardy–Weinberg equilibrium assumptions, 81% of the individuals are homozygous for a recessive allele. What percentage of the individuals would be expected to be heterozygous for this locus in the next generation?
