How gametes are created in the process of meiosis
By: Joshua Horn - 257112
Through meiosis, sexually reproducing organisms create gametes that house half of their genetic material. These gametes are then combined with the gametes of their mate to form the first cell of the offspring organism. It allows for stable reproduction producing two half sets of the...

Meiosis is the process by which sexually reproducing organisms create gametes that house half of their genetic material, to be combined with the genetic material of a mate. It allows for stable reproduction producing two half sets of the genome so that, through reproduction, a...
