A SNP marker is found linked to the cystic fibrosis gene. Cystic fibrosis is an autosomal recessive disease. A couple plans to have children together and both are carriers for the cystic fibrosis gene but do not have the disease themselves. They are both A1/A2 at the SNP and the A2 allele is linked with the allele causing cystic fibrosis. Assuming no crossing over between the SNP and the disease gene, what genotypes in the offspring could result that would cause cystic fibrosis? O A1-cf, A1 - cf O A2 - cf, A2 - cf

Question
A SNP marker is found linked to the cystic fibrosis gene. Cystic fibrosis is an autosomal recessive disease. A couple plans to have children together
and both are carriers for the cystic fibrosis gene but do not have the disease themselves. They are both A1/A2 at the SNP and the A2 allele is linked
with the allele causing cystic fibrosis. Assuming no crossing over between the SNP and the disease gene, what genotypes in the offspring could result
that would cause cystic fibrosis?
O A1-cf, A1 - cf
O A2-cf, A2 - cf
O A1 - CF, A1 - CF
O A1 - CF, A2 - cf
