Use the following information to answer the questions below. Tay-Sachs disease is an inherited genetic disorder in which the gene sequence codes for an enzyme involved in lipid metabolism.Accumulation of lipids in the brain leads to seizures,blindness,loss of neural function,and early death.People can be carriers of this disease and only homozygotic offspring will die from this disorder. -How can you reconcile these conclusions?
A)These alleles are really displaying incomplete dominance. B)There is a polygenic effect, where another gene encodes for the same enzyme. C)This is a result of epistasis. D)The observed dominant/recessive relationship of alleles depends on the level at which the phenotype is examined. E)The observed dominant/recessive relationship of alleles only applies at the organismal level.
