According to a recent study, 1 out of 50,000 people will be diagnosed withcystic fibrosis. Cystic fibrosis can be caused by a mutant form of the CFTR gene(dominant gene symbol is F and mutant is f).A. Using the rate of incidence above, what is the frequency of carriers of thecystic fibrosis allele for CFTR in the US? (3 pts)B. In a clinical study, 400 people from the population mentioned in (A.) weregenotyped for BRCA1 Listed below are the results. Are these results in Hardy-Weinberg equilibrium? Use Chi Square to show whether or not they are. (3 pts)BRCA1 genotype# of women390BBBbbb10012ptParagraphLBIUAV VT² vV

A pedigree analysis was performed on the family of a man with schizophrenia. Based on the known concordance statistics, would his MZ twin be at high risk for the disease? Would the twins risk decrease if he were raised in an environment different from that of his schizophrenic brother?
Studies have shown that there are significant differences in cancer rates among different ethnic groups. For example, the Japanese have very high rates of colon cancer but very low rates of breast cancer. It has also been demonstrated that when members of low-risk ethnic groups move to high-risk areas, their cancer risks rise to those of the high-risk area. For example, Japanese who live in the United States, where the risk of breast cancer is high, have higher rates of breast cancer than do Japanese who live in Japan. What are some of the possible explanations for this phenomenon? What factors may explain why the Japanese have higher rates of colon cancer than do other ethnic groups?
