carrier rate for CF is 1/25
what is the incidence of the disease?
Ans: according to kaplan : 1/25 * 1/25
accor to goljan : 1/25 * 1/25 * 1/4
what is the truth?
carrier means (HE equilibrium) 2pq = 1/25; p=1 for rare disease ---q=1/50. for AR disease have to be homozigot to have the disease so incidence= q2 ------1/2500.
