<u><em>Genetic variation</em></u> occurs because beneficial traits exist in a collection of genes, and <u><em>gene flow</em></u> makes these traits more prevalent in populations.
Explanation:
In biology, genetic variation can be described as the different genotypes which occur in species of the same kind. This genetic variation allows those organisms to survive on Earth which are better adapted to survive to the environmental changes.
The organisms which are better adapted to live in an environment will reproduce and pass their traits to the offsprings. Over time, these traits will become more prevalent in a population.

The chondrioma of a cell is the set of 300 to 800 mitochondria (from 1000 to 3000 in muscle cells, 2500 of which in a parenchymal cell of the liver or, which is a smooth muscle) which constitute up to 25% of the cell mass.
Very numerous in young cells and / or very active, which require a lot of energy (like spermatozoa), mitochondria are organelles because they constitute functional units of the cell: they are the "energy factories". Omnipresent in any animal or plant cell, mitochondria exist even in anucleate blood thrombocytes.
