How does meiosis introduce genetic variation into offspring?

(1) Answers

Genetic variation is introduced as a result of the distinct crossing over of chromosomes in both phases of prophase. In the meiosis process, there can also be mutations in the s phase which are very unpredictable and can result in some very significant variations depending on where the coding is. by independent assoartment and 3 by mutations in s phase. Because of the way that meiosis is set up it allows for the offspring to be either very similar to the parents or can even be very different from these factors.
