Law of segregation


The separation of an individual's two genes at a locus into its offspring is called segregation.

Mendel (pictured opposite) demonstrated that, for every character, an organism inherits an allele from each of its two parents. The law of segregation - also known as Mendel's First Law - holds that an organism passes genes from mother and father into the gamete with equal frequency.

Mendel's Second Law, which states that the inheritance of one trait is independent of others, is known as the law of independent assortment.
