can someone explain when meiosis occrus in relation to spermatagenesis (sp?) and oogenesis? I'm doing a project about turner syndrome and need to know how it occurs.....

Since this is not my area of expertise, I searched Google under the key words "'Turner syndrome' meiosis stage" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. If not, you can continue the search using the above key words. Thanks for asking.
