If a dominant disorder is described as being 80% penetrant, what would this mean? O The amount of expression within individuals varies O The disorder is present in 20% of the individuals that have the dominant allele O 20% of the individuals who have the dominant allele may have genes that mitigate (prevent) the disorder and therefore do not display symptoms O The trait is present in 80% of the total population.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
