Mutations and Genetic Diseases
... Having one set of genes from each parent can result in a decreased incidence of genetic disease. In many genetic diseases, symptoms are associated with a mutation. The inheritance of a non-mutated copy of a gene from one parent can often compensate for the mutations present in the gene inherited f ...
