This is a genetic question:
6. John and Mary each have sisters with cystic fibrosis. They would like to marry and have
children, but are concerned that they too may have a child with cystic fibrosis. Cystic fibrosis is
an autosomal recessive disease located on chromosome 7. If John and Mary are each
heterozygous for cystic fibrosis what is the probability of:
A. Having 2 normal children and 2 affected children in any order?
B. Having 3 normal children and 2 affected children in any order?.
