The dominant facial features include an oval-shaped face, widow's … WebSingle-Gene Defects. Genetic disorders determined by a single gene (Mendelian disorders) are easiest to analyze and the most well understood. If expression of a trait requires only one copy of a gene (one allele), that trait is considered dominant. If expression of a trait requires 2 copies of a gene (2 alleles), that trait is considered recessive.

WebMay 5, 2024 · Caused by an inherited defect in a single gene, the disease is an autosomal dominant disorder, which means that a person needs only one copy of the defective gene to develop the disorder. Each parent with a defective gene could pass along either a defective copy or a healthy copy, leaving a child with a 50% chance of inheriting the disease. WebNov 7, 2024 · Two primary factors influence the likelihood a person will inherit a genetic disorder: Whether one copy of the mutated gene (from either parent) is passed down or whether two copies (one from both parents) are passed down.
