WitrynaSelect all of the following that are traits typical of autosomal recessive inheritance. Two affected parents always have affected children. Males and females affected with equal frequency. The trait often skips generations. Close relatives who reproduce are more likely to have affected offspring. Tay–Sachs disease is an autosomal recessive genetic disorder, meaning that when both parents are carriers, there is a 25% risk of giving birth to an affected child with each pregnancy. The affected child would have received a mutated copy of the gene from each parent. If a child received a normal copy from one parent and a mutated copy from the other, it is a carrier.

WitrynaTay–Sachs disease is an autosomal recessive, progressive neurodegenerative disorder that begins in infancy. It is caused by a mutation in the alpha subunit of the hexosaminidase A gene (HEXA) that results in the accumulation of ganglioside GM2 in nervous tissue leading to cell damage.
