Cystic Fibrosis Is a Genetic Disorder in Homozygous Recessives That

Cystic fibrosis is a genetic disorder in homozygous recessives that causes death during the teenage years.If 9 in 10,000 newborn babies have the disease,what are the expected frequencies of the dominant (A₁) and recessive (A₂) alleles according to the Hardy-Weinberg model?

A) f(A₁) = 0.9997,f(A₂) = 0.0003
B) f(A₁) = 0.9800,f(A₂) = 0.0200
C) f(A₁) = 0.9700,f(A₂) = 0.0300
D) f(A₁) = 0.9604,f(A₂) = 0.0392
E) f(A₁) = 0.9600,f(A₂) = 0.0400
