WebHow is it that dominant lethal genes, such as the one that causes Huntington's disease, can persist in a population? a) The disease-causing allele can "hide" in the heterozygous condition. b) The disease develops only under the influence of other genes. Web26 jun. 2010 · A person with Huntington’s disease has one non-HD allele and one HD allele.
