Meiosis; Biology

-chromatids form tetrads with homologous chromosomes and crossing over or recombination takes place

-homologous chromosomes line up on opposite sides of equatorial plane

-homologous chromosomes line up independently of the other resulting in independent assortment

homologous chromosomes are seperated

-sister chromatids remain together

nuclear envelope reforms resulting in Haploid daughter cells

nuclear envelope dissolves

chromosomes line up in the middle

-sister chromatids are split apart

four haploid daughter cells formed

when tetrad chromatids exchange genetic information mixing paternal and maternal DNA

-happens in prophase I

In metaphase I, chromosomes line up randomly increasing genetic variation
