34. Huntington's disease is a disease of the nervous system that is caused by a dominant allele (H). Although Huntington's disease is relatively rare around the world, affecting about I in every 10,000 people, in the small village of Barranquitas in Venezuela, Huntington's disease is much more common. In the population of 4,094 people in Barranquitas, 411 have Huntington's. What is the frequency of Huntington's disease in Barranquitas? 411/4094 0.100 B. What is the frequency of the normal phenotype? 1-0.100 0.900 C. What is the allele frequency of h? h^2-0.100 0.316 D. What is the allele frequency of H? 1-0.316= 0.684 What is the frequency of people who are heterozygous? 2(0.316)(0.684)=0.432 F. How many people are homozygous dominant? Е. G. How many copies of the recessive allele are there in the population? H. How many people carry at least one recessive allele?
