Prophase I or metaphase I

Postby aaronsharpe » Sun Sep 16, 2007 7:07 pm

Hello, I'm quite new here and I'm not quite sure if this is in the right place but here goes.

Can someone please tell me during what phase of meiosis I the bivalents align along the equator of the cell?

One book I have says they move towards the equator during late prophase I and then align during metaphase I. Another book says they move and align only during metapahse I.

Thanks in advance

well do you know what metaphase is? metaphase is defined as "the stage when the chromosomes are at the equator of the cell". they start to move towards the equator of the cell in prophase. when they arrive at the equator, prophase has ended and the cell is in metaphase

Thanks. That definition is a lot more concise than the one they taught me in college.
