SURVEY . autosomal dominant Genetics Referring to a mode of inheritance, in which the presence of only one copy of a gene of interest on one of the 22 autosomal–non-sex chromosomes, will result in the phenotypic expression of that gene; the likelihood of expressing an autosomal gene in progeny is 1:2; ♂ and ♀ are affected equally. A person with an autosomal dominant disorder — in this case, the father — has a 50% chance of having an affected … Tags: Question 6 . In an autosomal dominant disorder, the mutated gene is a dominant gene located on one of the nonsex chromosomes (autosomes). Autosomal dominant disorders include all the following EXCEPT .
