WebbTay–Sachs is an inherited disease caused by a recessive allele (t). The Punnett square shows the genotypes of a male and female and the predicted genotypes for their offspring. What is the probability, in percent, that a child born to these parents will inherit Tay–Sachs disease? 04:51 Video Transcript WebbThe genetics of Tay-Sachs disease. The genes in our cells are in pairs. We inherit a set from each of our parents. TSD follows an autosomal recessive inheritance pattern. This means that: the affected gene is on one of the non-sex chromosomes ; both copies of the gene need to be altered for a person to have the condition.
