meiosis

[wannabdoc1]

got a question,

What stage of meiosis does crossing over occur?

Prophase 1 or Metaphase 1?

Kaplan subject test 2 Q19 says its Prophase 1 but I know I have put down metaphase 1 before and have gotten it right. I think its metaphase 1.

It is prophase I....in meiotic metaphase I tetrads align instead the replicated sister chromatids.

Definitely prophase I.
