    I've read several places that say it occurs only in tetra formation during Meiosis Prophase I. Other places suggest it happens in Meiosis Metaphase. I originally thought metaphase. Any definite answer here?

    I had this question on the real DAT.

    The answer was Meiosis Prophase I.

    I wouldn't worry about these substages...the DAt won't test on them unless they suddenly decided last week to make the test 10000% harder.

    Just remember that Crossing Over occurs in Prophase I of meiosis, and you be fine...just watch out for the trick answer:

    c) on late night TV with John Edwards

    this is a trick aswer...do not fall for it.
