Agenetics question: tay-sachs disease is a rare human disease in which toxic substances accumulate in nerve cells. the recessive allele is inherited in a simple mendelian manner. a woman is planning to marry her first cousin, but the couple discovers that their shared grandfather's sister died in infancy of tay-sachs disease.
what is the probability that the cousins' first child will have tay-sachs disease, assuming that all people who marry into the family are homozygous normal?
i'll draw the pedigree i have and the work i've done - can't seem to get the right answer, though.
