Use the Hardy-Weinberg Principle to complete the assignment. Show your work. 1. In a large, random-mating population with no forces acting to change gene frequencies, the frequency of homozygous recessive individuals for the characteristic of extra-long eyelashes is 90 per 1000 individuals. What is the frequency of the recessive allele? ______________________ What is the frequency of the dominant allele? _______________________ What is the frequency of the heterozygous individual? ________________ 2. Allele A is present in a large random mating population at a frequency of 54 per 100 individuals. What is the frequency of allele a? __________________________ What is the proportion of individuals in the population expected to be homozygous for A? _________________________________ What is the proportion of individuals in the population expected to be homozygous for a? ____________________________ What is the proportion of individuals in the population expected to be heterozygous? ________________________________ 3. The North American human population is similar to the ideal Hardy-Weinberg population in that it is very large and generally random-mating. (Mutation and migration are relatively minor forces.) The scientist, Randy M. Mateng, analyzed a group of individuals for a blood type called the MN blood typing. His results are as follows: MM MN NN Observed individuals 3210 4670 2120 What is the frequency of the M allele? ________________________ What is the frequency of the N allele? ________________________ What would the frequencies be 10 generations from now? M __________ N _____________ 4. Cystic fibrosis is a recessive disease that primarily affects Caucasian individuals. In the American population the frequency of the allele for cystic fibrosis is 22 per 1000 individuals. What is the frequency of the cystic fibrosis allele? _______________________ What is the frequency of the normal or dominant allele? ____________________ What percentage of the population will have cystic fibrosis? ________________ What percentage of the population will be a carrier (heterozygous)? ___________ 5. Phenylketonuria (PKU), a genetic disorder due to homozygosity for a certain recessive allele, occurs in about 1 person in 15,000. What is the frequency of the PKU allele? ______________________________ What is the frequency of the normal allele? _____________________________ What is the frequency of the carrier (heterozygous) individual? ______________ 6. In the United States, about 45% of the white population has blood type O, 41% type A, 10% type B, and 4% type AB. Determine the frequencies of the three alleles of the ABO blood type. (Hint: Type A blood can be either AA or AO; type B blood can be either BB or BO; type AB is AB; type O is OO.)
