Huntington's disease is a very rare, debilitating disease that affects approximately 1 in 10,000 people. The disease is caused by a particular type of genetic mutation (large number of CAG repea n a gene called huntingtin (HTT). Designate the disease-causing allele HTTD and the non-disease- causing allele HTTN. We know that individuals with genotype HTTN will not develop Huntington's Disease, but people with either HTTP/HTTD or HTTN/HTTD will develop the disease. Which allele is dominant--HTTN or HTTD? Explain your reasoning thoroughly, using the correct definition of dominance
