How many times do cells undergo Mitosis in order to become a gamete?

Cells do not undergo mitosis to become gametes although Somatic Cells go through Mieosis 1 & 2 to become gametes.

Explanation:

Specifically a somatic cell is split twice where on parent cell ends up into 4 daughter cells through Meiosis 1 and 2

Mitosis produces the exact same cell so if you did mitosis on a somatic cell it would never happen. But if you did it on a cell already a gamete it would only take one division

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.
