Question
Can someone explain 22?
21. Tyrosinemia is a recessive disease in which the liver fails to produce an essential liver enzyme. Individuals with tyrosinemia usually survive less than 4 years (unless a liver transplant operation is done). Tyrosinemia occurs in about 1 in 12,000 children born in the US. What is the frequency of heterozygotes for this disorder? a. 0.0083 b. 0.00913 c. 0.00083 d. 0.0181 e. 0.003
22. Assuming that a third of the tyrosinemia affected individuals can successfully undergo a liver transplant (W22 = .33), what will be the frequency of the recessive allele after one generation of this selection? a. 0.00916 b. 0.00769 c. 0.00937 d. 0.00898 e. 0.01778
