2 answers:
Answer:
c. Crossing over
Explanation:
In meiosis, crossing over refers to the process where<u> homologous chromosomes 'combine' with each other in order to exchange genetic material</u>, which results in genetic variation. This process takes place during Prophase I of the <u>first meiotic division</u>.
Crossing over is extremely important for the variation - and survival - of a species, as it results in numerous genetic combinations that are passed from generation to generation.
