A. Autosomal dominant is a pattern of inheritance in genetics where only one copy of a mutated gene on an autosome (a non-sex chromosome) is sufficient to cause a particular trait or disorder. Here are the key points: 1. **Single Mutated Gene**: In autosomal dominant inheritance, a person only needs one copy of the altered gene from one parent to inherit the trait or disorder. 2. **Equal Transmission**: The trait or disorder can be passed from either the mother or the father and affects both males and females equally. 3. **Generational Occurrence**: Autosomal dominant conditions often appear in every generation of a family. Each child of an affected parent has a 50% chance of inheriting the condition. Examples of autosomal dominant disorders include Huntington's disease, Marfan syndrome, and certain types of familial hypercholesterolemia.
