Question

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 hardyweinberg model?

Answer 1

The expected frequencies are f(A1) = 0.9700, f(A2) = 0.0300 according to the Hardy-Weinberg model. For biologists studying a large flatworm population in the lab, which Hardy-Weinberg condition is most difficult to meet there is no mutation. It is called a genetic disorder in homozygous recessives that causes death during the teenage years.
