Egg and sperm cells are
generated through a type of cell division called meiosis. Meiosis is
a fundamental part of the life cycle of organisms that reproduce
sexually, such as humans. Meiosis reshuffles chromosomes, creating
genetic variation. The genetic diversity resulting from the meiotic
cell division allows natural selection to operate.
In this Lesson, we're going to
learn about meiosis. We'll also explore several types of asexual
We'll discuss how both sexual
and asexual reproduction can be evolutionarily advantageous in
different environmental situations.
