Central dogma of molecular biology - Wikipedia

The central dogma of molecular biology is an explanation of the flow of genetic information within a biological system. It is often stated as "DNA makes RNA, and RNA makes protein", although this is not its original meaning. It was first stated by Francis Crick in 1957, then published in 1958:. The Central Dogma. This states that once "information" has passed into protein it cannot get out again.

Recessive Inheritance - Genetics Generation

Recessive Inheritance. When a trait is recessive, an individual must have two copies of a recessive allele to express the trait.Recessive alleles are denoted by a lowercase letter (a versus A). Only individuals with an aa genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait.
