Meosis

What happens during Interphase?

• DNA is replicated and attached to each other at the centromere

• tetrads form

• spindle fibers attach

• cytokenisis

What happens during Prophase 1?

• spindle forms

• tetrads form and crossing DNA

• independent assortment

What happens during Metaphase 1?

• sister chromatids attached at their centromeres

• synapsis occurs and exchange DNA

• tetrads line up and independent assortment occured

What happens during Anaphase 1?

• sister chromatids line up in the middle

• spindle fibers pull the tetrads apart while the sister chromatids remain attached

• cells divide

What happens during Telophase 1?

• 2 distinct poles of the cell begin to form with one set of non-identical DNA on each side

• DNA is exchanged

• nuclear membrane dissolves

What happens during Prophase 2?

• Spindle fibers pull in the tetrads apart

• the start of Meiosis 2 and the nuclear membrane dissolves and the spindle fibers form

• spindle fibers pull the sister chromatids apart and they seperate

What happens during the Metaphase 2?

• cells divide

• haploid

• sister chromatids line up in the middle

• random genetic variation

• DNA is replicated
