this week we learned about meiosis. the phases are..

• prohase I-non-sister chromotids connect and trade sections.
• metaphaseI- spindle fibbers attach to each dyad at the kinerachore.
• anaphaseI-chiasmata break apart and sister chromotids go to migraring towards oppiste poles
• telophaseI-cleavage furrow forms. cell splits
• prophaseII-spindle formation begins.
• metaphaseII-tension from spindle fibers
• anaphaseII-chromotids separate and begin moving to the poles
• telophaseII-cleavage furrow forms

meiosis is important in sexual reproduction. meiosis makes sperm and egg cells.

we also learned a new vocabulary word.

• autosomes-all the other 22 pairs of chromosomes that aren't the sex chromosomes.

the sex chromosomes are called x and y. the males carry either the x or y chromosome. females only carry the x chromosome. if you get 2x's then the baby would be a girl. if you get a x and a y then it would be a boy.
