Genetic variation is a strong driver of evolution in species. Organisms that use sexual reproduction have evolved a cell division process known as meiosis to increase genetic variation in their offspring.

crossing over during prophase I and independent assortment during metaphase I
crossing over during prophase I and independent assortment during metaphase I

independent assortment during prophase II and crossing over during metaphase II

Answer 1

The correct response is:

crossing over during prophase I and independent assortment during metaphase I.

These two processes contribute to genetic variation: crossing over allows for the exchange of genetic material between homologous chromosomes, and independent assortment refers to the random distribution of different chromosome pairs during meiosis.
