Spermatogenesis and Oogenesis Question

Hey everyone!

I want to see if I have the chromosome. chromatid numbers down for both oogenesis and spermatogenesis. Is this right?

Spermatogenesis:
-Spermatogonia: 2N, 46 single chromosomes, 46 chromatids
-Primary Spermatocyte: 46 chromosomes, 92 chromatids, 2N
-Secondary Spermatocyte: 23 chromosomes, 46 chromatids, N
-Spermatids: 23 chromosomes/ chromatids, N

Oogenesis:
-Oogonia: 2N, 46 single chromosomes/ chromatids
-Primary oocyte: 2N, 46 chromosomes, 92 chromatids
-Secondary oocyte/ first polar body: N, 23 chromosomes, 46 chromatids
-Egg/ second polar body: N, 23 chromosomes/ chromatids

Is this right??

Thanks in advance!

I hope so! The randomness of the bio section is just crazy haha.

It's not really that random. You have all the materials necessary. It's really more face value questions. More like what hormone stimulates ovulation type of questions.

Hmm I see what you mean. Do you happen to know if what I have above is right by any chance?

im most likely sure that you are right.

also know that in oogenesis:

stops at prophase I when you are an infant
then proceeds to metaphase II when you are in puberty
and ONLY it will complete meiosis II when fertilization occurs
