Each person carries 23 pairs of  chromosomes in every cell that makes up their body, with the exception of gametes, which contain 23 SINGLE chromosomes. So when a sperm and egg meet, they then have 23 pairs. In the process of meiosis 'crossing-over' occurs, which means that the chromosomes get "shuffled". This means that the child can receive random traits not only from the parents, but also the grandparents. so there is about  2⁴⁶ possible pairings, excluding the risk for things such as Down-Syndrome

Tay-Sachs disease results from ______ lacking a specific type of lipid-digesting enzyme.
Virty [35]

Answer:

Tay-Sachs disease results from brain lacking a specific type of lipid-digesting enzyme.

Explanation:

Tay-Sachs disease occurs when relatively large amounts of gangliosides are stored in the brain. It is the oldest lipid storage disease and is a hereditary disorder caused by deficiency of a lipid-digesting enzyme known as "hexosaminidase A", which cleaves a specific bond in the gangliosides.

Its deficiency cause accumulation of gangliosides in the lysosomes of BRAIN CELLS thereby causing degeneration of the nervous system.
