What type of inheritance pattern does Tay-Sachs follow?

WebDihybrid cross is the mating of two organism following the inheritance of two traits. Test cross is used to determine the genotype of a dominant phenotype by crossing the unknown genotype with a homozygous recessive. Tay-Sachs disease results in the inheritance of two copies of the affected trait, this would be a monohybrid cross. Question 3.

WebTay-Sachs disease is the major model for lysosomal storage diseases.

Absence (or near absence) of enzyme activity is required to damage neurons; neurons that have approximately half-normal activity are unaffected. Thus, TSD is autosomal recessive, requiring HEXA disease variant(s) on both paternally and maternally inherited genes (homozygosity or compound …
