builgate Posted October 29, 2005 Share 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 Link to comment Share on other sites More sharing options...
AlbatrosKill Posted October 29, 2005 Share Posted October 29, 2005 What does descared mean? Link to comment Share on other sites More sharing options...
builgate Posted October 31, 2005 Author Share 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?
