P1

chromatin condenses to form cms made up of 2 = SC held tgt @ ctm > HC pair up to form bivalent->synapsis > crossing over occur b/w non-SC of HC > sections of cmt w/ = genes break,rejoin give new combinations of alleles, forms RC

M1

cms arranged along metaphase plate in bivalents > IA of HC, arrangement of cms of each bivalent independent of others

A1

HC pulled to opp poles of cell when SF attached to ctm shorten, contract

T1

HC reach opp poles of cell, uncoil, lengthen, becomes indistinct to form chromatin

P2

chromatin condenses to form cms made up of 2 cmt held tgt @ ctm

M2

cms arranged in single row on metaphase plate > IA of cmt, arrangement of cmt of each cms independent of others

A2

ctm divide, cmt separate @ centromere > each cmt now daughter cms, pulled to opp poles of cell

T2

DC reach opp poles of cell, uncoil, lengthen, becomes indistinct to form chromatin
