How does meiosis result in genetic variation?

HideShow resource information

The suffling of existing genetic material into new combinations during meiosis is important in creating genetic variation.

This shuffling includes:

  • independent assortment
  • crossing over

Independent assortment:

  • during meiosis only one chromosome from each pair ends up in each gamete
  • the independent assortment of the chromosome pairs as they line up during meiosis 1 is a source of genetic variation
  • this process is random; either
