Genetics Basics: Modes of Inheritance

There are multiple methods of inheritance that determine which characteristics (or phenotypes) are displayed by the offspring, including autosomal dominant, autosomal recessive, and sex-linked inheritance. There are also many polygenic traits (i.e., associated with multiple genes) as well as environmental factors that make it much more complicated to predict disease or the likelihood of passing disease onto offspring.
