Question Answered step-by-step 5. A population has 1,000 individuals with the following genotype… 5. A population has 1,000 individuals with the following genotype frequencies: 275 = AA, 550 = Aa, and 175 = aa. What are the allele frequencies? 6. In a population of 10,000 insects, 75 percent have the dominant phenotype. What are the allele frequencies of A and a? 7. If a population of beetles has an allele frequency of A = 0.7 and a = 0.3, then what are the expected genotype frequencies? 8. If 42 percent of fruit flies in a population of 1,000 have the dominant phenotype of long wings, then what are the allele frequencies for A (long wing allele) and a (short wing allele)? 9. Cystic fibrosis (CF) is one of the most common genetic diseases among Americans. CF occurs in approximately 1 in every 3,400 births in the United States (estimates vary). A. If 1/3,400 people have CF, then what percentage of the population carries this trait? B. If two carriers of CF get married, then what is the chance that their offspring will have CF? C. If any two random people in the United States have a child, then what is the chance that their child will have CF? 10. Ashley has a sister with CF, but neither Ashley nor her parents have the disorder. CF is caused by a recessive allele. Steven also has a sister with CF and neither Steven nor his parents have the disease. If Ashley and Steven get married, what is the chance that they will have a child with CF? (Hint: What is the chance that Ashley and Steven are carriers?) 11. In a population that is in Hardy-Weinberg equilibrium, the frequency of the recessive homozygote genotype of a certain trait is 0.09. Calculate the percentage of individuals homozygous for the dominant allele.  Science Biology SCIENCE AP Share QuestionEmailCopy link Comments (0)
