Finding Co-Inheritance of an SNP Variant and a Disease Tells

Question

Finding co-inheritance of an SNP variant and a disease tells scientists that
A)everybody who carries this SNP will get the disease.
B)sequences within the SNP cause the disease.
C)a gene important for causing the disease is linked to the SNP.
D)SNPs on other chromosomes will not be co-inherited with the disease.

Accepted Answer

Co-inheritance of an SNP variant and a disease indicates that the gene associated with the disease is located close to the SNP and may be inherited together. It does not necessarily mean that everyone who carries the SNP will get the disease or that the SNP itself causes the disease. Co-inheritance with a disease also does not imply anything about SNPs on other chromosomes.
