ARE THE XX AND XY CHROMOSOMES SEPARATED

Postby poonisha » Wed Jun 01, 2005 7:49 pm

Are xx and xy chromosomes separated in males testes or are they all combined. Or maybe all the x's in one sack and all y's in the other? Please help I'm trying to determine if I would be able to have a baby girl after 4 boys. My husband only has one teste. How does this work?

There are got nothing to do with number of testes( Matter of amount of the sprematozoa produced) . Both testes also produce same gametes of spematozoa in meiosis process which separate the homologous chromosomes. That will divide the gametes into 2 in meiosis 1 and to 4 in meiosis 2 which lead to an equal distribution of chromosomes to the gametes and in other words from diploid(2n) to haploid(n) which this will divides the x and y chromosomes into separate cell or gamet( separate sprematozoa in meiosis process). Possiblitiy of getting girl is depend to your husband's testes reproducetive system( about quantities of sprematozoa produced) and the chances of swimming spermatozoa( specific XX) which will survive inside the vagina and last can survive to penetrate the ovum.
And i heard nowdays the medicine faculty have a research that we can determine and have either boy or girl for our baby but banned in some countries.

You can not decide the baby's sex on your own. Actually the father's chromosomes decide the sex of the baby. And it has nothing to do with the number of the testes. And yes you may have a baby girl. ( not guaranteed)
To sum up, unfortunately, you can not do anything about that.
By the way, I hope you will have a baby girl... :)

XX and XY

I think that XX actually is one chromosome and you can't determine to your soon to be born baby (except you do cloning that is still controvercial till now). As Poison said that testical organ only affect on reproducing sperm. I hope that you get what you deserved.

No, it's not. there are 2 chromosomes.

Sounds like a line from a soap-opera. :D :D
Good luck with that child, poonisha
