Genetic variation of individual chromosomes occurs during genetic variation of individual chromosomes occurs during metaphase i anaphase i prophase i prophase ii

Prophase I

this occurs duirng meiosis in which the cell division that results in four daughter cells each with half the number of chromosomes of the parent cell which occurs in the production of gametes. The chromosome exchange genetic information called the chromosomal crossover during the first division in Meiosis I. The daughter cells will divide again in Meiosis II, splitting up sister chromatids to form haploid gamete.
