The following data for the genotypes at the alcohol dehydrogenase locus were observed from a sample of Drosophila melanogaster. Sample size 1000 FF 550 FF=0.55; FS=0.34; SS=0.11 O F-0.72; S=0.28 FF=0.078; FS=0.40; SS=0.52 FS What are the Hardy-Weinberg equilibrium genotype frequencies for each genotype based upon this sample? OFF=0.52; FS=0.40; SS=0.078 340 SS 110

Biology Question

a) Suppose the frequency of the recessive allele a for the recessive condition albinism is 0.2 Assume the Hardy-Weinberg distribution.    ai) What is the frequency of albinism in the general population?  aii) What fraction of the population are carriers?  b) In a large population of mice, 0.58 have the recessive genetic condition rsiancer (fictional).  Assume the Hardy-Weinberg distribution. What fraction of mice are carriers? Giver your answer with two digits parts the decimal point. c) In a large population of squirrels,  0.14 have the recessive genetic condition nlourianfilindr (fictional).  Assume the Hardy-Weinberg distribution.  What is the frequency of the dominant allele in this population? Give your answer with two digits parts the decimal point. d) In a large population of chimpanzees,  there is a recessive genetic condition telactalase (fictional).  Assume the Hardy-Weinberg distribution.  If the frequency of dominant allele is 0.77 then what fraction of the population has…
