Biology - Meiosis Flashcards

A type of cell division that results in two daughter cells each with half the chromosome number of the parent cell

Meiosis is often called reduction division because the genetic material is reduced - by half.

A series of safeguards ensures the DNA is intact and that the cell is functioning normally.
