builgate Posted October 29, 2005 Posted October 29, 2005 I have taken the following question from Internation Biology Olympiad. I can't figure out the answer yet. 45 In the European population, about 1 in 2500 people suffers from Cystic Fibrosis, a genetically determined (descared), autosomal disease. Healthy parents have a child suffering from Cystic Fibrosis. The woman remarries a healthy man. What is the chance of a child from this second marriage suffering from Cystic Fibrosis: A 1 : 25 B 1 : 50 C 1 : 100 D 1 : 625
builgate Posted October 31, 2005 Author Posted October 31, 2005 I am not sure what "descared " mean. It is taken from the original question paper. I am thinking how to calculate the possibility of getting a "healthy man" ( i think it includes the homozygous and carrier) in the second marriage?
