steps Of Meiosis 2 Flashcards
does meiosis two have interphase?
no DNA duplication between meiosis one and two
Each new cell now only has a total of 46 chromosomes
what happens in prophase II in meiosis two
Spindle fibres form again and nuclear membrane breakdown
what happens in metaphase II in meiosis two?
Sister chromatids lineup along the equator of the cell
What happens in anaphase II in meiosis two?
Sister chromatids move to opposite poles
what happens in telophase II IN MEIOSIS TWO?
Cells pinch in
spindle fibres disappear
nuclear membrane reforms
chromosomes become uncondensed and chromatin again
what happens in cytokinesis?
Produces 4 cells each containing 23 chromosomes
what is the random assortment of Home religious chromosomes?
Chromosomes in each pair or assorted independently
