1.A newspaper story on AIDS reports that an allele (R) conferscomplete resistance to HIV when homozygous and that 2% of the humanpopulation is resistant (RR). The story also states that 18% of thepopulation carries one copy of the resistamnce allele (i.e., isheterozygous). Is this a guess, an approximation, or an exactfrequency, assuming that the population is at Hardy-Weinbergequilibirum? Show calcualtions indicating the values of p and q andall work.
2.A new kind of tulip is produced that develops only purple orpink flowers. Assume that flower color is controlled by asingle-gene locus , and that the purple allele (C) is dominant tothe pink (c). A random sample of1000 tulips from a large cultivatedfeild yeilds 812 purple flowers and 188 pink flowers.
A) Determine the frequency of the purple and pink alleles in thisfield population.
B) Estimate the proportion of all purple flowering plants that areheterozygotes and homozygotes.SHOW ALL CALCULATIONS.
3. You are studying a single-gene locus with two alleles inapopulation that is in Hardy-Weinberg equilibrium. Examination of alarge sample of individuals from the population reveals there arefive times as many heterozygotes as there are homozygote recessiveindividuals in this population. What is the frequency of therecessive allele? SHOW ALL CALCULATIONS.
