produces cells that are genetically different from the parent cell
can be used for sexual reproduction


Sexual reproduction
the offsprings are genetically different from each other and from the parents
each parent produces special reproductive…

Genetic variation
Meiosis and germline fertilisation increase genetic variation in a number of ways:
through the process of crossing over during prophase I (this occurs where alleles can be
shuffled between chromosomes where they cross over at points called chiasmata)
through genetic reassortment due to the random distribution and subsequent…
