Question

individuals with tay-sachs disease, a recessive genetic disorder, usually die at a young age. why dont individuals with tay-sachs disease pass on the tay-sachs allele?
a affected individuals do not have children.
b carriers are not affected.
c the recessive allele does not stay in the gene pool.

Explanation:

Tay-Sachs disease is a recessive genetic disorder causing early death. Affected individuals typically die young, so they do not live long enough to have children and pass on the allele. Option b is about carriers (unaffected), which is irrelevant to why affected individuals don’t pass the allele. Option c is incorrect because the recessive allele remains in carriers in the gene pool.

Answer:

a. Affected individuals do not have children.
