Diagram Explanation














PROPHASE I
















 The chromosomes begin to condense and

become ________and _________

 The ____________chromosomes come

together to form bivalents through a

process called ______________

 Each homologous chromosome is made up of

two sister _____________

 Exchange of segments of DNA occur between

non-sister chromatids in a process

called ________________

 The points at which segments of chromatids

cross over are called ___________

 At the end of this stage, the nucleolus and the

nuclear ___________disappear.

 The two pairs of centrioles migrate to the

opposite pole of the cell which then act

as central points from which the ___________

______________ appear.









___________

 The chromosomes are lined up side by side as

tetrads on the metaphase _________

 The _________________ does not divide

ANAPHASE I














 The _______________ chromosomes

separate and are pulled away by the spindle

fibres to the opposite poles of the cell.

 Although the cell started with 4

chromosomes, only _________

chromosomes move towards each pole.










TELOPHASE I









 The chromosomes arrive at the

_____________

 Each daughter nucleus now has a

___________ number of chromosomes

( only one set of chromosomes/ no more

homologous chromosomes )

 The spindle fibres disappear.The

___________ ____________ reappears to

surround each set of chromosomes, followed

by the ____________ process.





CYTOKINESIS takes place







PROPHASE II






















 The nuclear membranes of the daughter cells

disintegrate again

 The spindle fibres reform




METAPHASE II


















 The chromosomes (each still made up of sister

chromatids) line up at the metaphase plate

 Each sister chromatid is attached to the

spindle fibres at the centromere.
