Huntington recessive or dominant

WebIf Huntington's Disease is a dominant pathology and two people who were homozygous recessive for the disorder (hh) were to have offspring, it would be impossible for their offspring to inherit the Huntingtin gene defect, as both parents would need to have at least one dominant allele (H) in order to pass it on to their offspring. WebDominant means that only one gene from one parent is necessary to pass down a trait or a disorder. When a parent has a dominant trait or disorder, there is a 50 percent chance that any child he or she has will also inherit the trait or disorder: Click Image to Enlarge What is Marfan syndrome?
