Meiotic drives

Definition

A phenomenon where a particular allele or chromosome is inherited by offspring more frequently than expected due to its preferential transmission during meiosis.

Etymology

From Greek 'meiosis' meaning 'lessening' and 'drive' meaning 'propel forward'.

Example

In some species of Drosophila, meiotic drive can result in an excess of offspring inheriting a specific chromosome even though it carries a detrimental allele.
