wow what an what an informa tative video video ive never ive never heard a video that sounds that sounds so interesting interesting that sounds so interesting to listen listen to it was was so so pleasant and smooth to smooth to listen to i cant be i cant believe everybody everybody doesnt listen to everybody doesnt listen to this video
I always thought homosexuality was hormonal, a type of brain-hermaphrodism like transgender and psuedo-hermaphrodites since we all start off in the same place anatomically inbetween, I assumed we must also start off in the same place in the brain inbetween male & female sexuality & gender identity.
Remember, this only applies to flies and closely related species. This does not apply to other organisms. In mammals, the y chromosome has the gene called SRY. This is the testis determining factor. In reptiles sex is determined by temperature, via temperature stability of a sex determining protein.
I'm a little confused about SRY in mammals, do they mean actual testis as in producing sperm and testosterone or gonads that have the potential of becoming testis, because some websites said gonads in fetuses have the potential of becomming either ovaries or testis by dropping down via hormone variations by the mother and receptors of the fetus, or do only xy males have the potential of developing testis?
SRY is the testis determining factor. There is no way that testis can be produced in mammals without SRY. To illustrate this, I bring up the example of Klinefelter's syndrome, that has the Karyotype XXY. These individuals are male, with a penis, testicles, however they exhibit feminine characteristics of developed breasts, minimal lactation, high pitch voice, little to no facial hair, etc. They tend to be infertile as well. Websites were wrong, testis can only be produced when SRY is present.
There's also another condition similar to Klinefelter's Syndrome called XX-male Syndrome. Experiencing a variety of symptomes including azoospermia, hypospadias, cryptorchidism, gynecomastia etc. which they commonlly find a Testis gene on one of the X-chromosomes possibly due to a translocationin of autosomes...
...So, Hormones activate cells, but it is the actual gene within the cell that is being activated, so Testis/SRY would have to be a gene existing in the chromosome in order for masculization to occur, and hermaphrodite variations occur due to the existance of SRY being simutaniosuly stimulated by different quantities of hormones in sex determination?
and It must be the same way with neurological genes regarding gender and sexuality?
That sounds about right, however not exactly conclusive. We have to show the molecular interactions, or find out if we already have. I know a lot less about human gender and sexuality than about molecular genetics, of which, homosexuality and gender in flies is but an example.
Sir, does this only apply to fruit flies and insecure heterosexual flies! I fear my own spermatazoan who may suddenly become maverack and torpedoe a fertile area in my gene pool and cause me to be the laughing stock of my neighborhood! Gene and Jean might be misunderstood as mutants of the gender slice if symptomatic in speed speaking to an amateur! double sex is bisexuality and a happy fly is a gay fly. little closet should be prodived and monitored diametrically transposed orally if asexual!
While this is very interesting you are reading your notes far to quickly and in a way that the vast majority of us who are not biologists or geneticists cannot possibly hope to follow.
But good vid, and the very fact that there is so much info compressed into it kinda proves my point to TheWay0987 that he shouldn't make statements based on pop-genetics alone when the reality is significantly more complex.
What a laugh.

So sex determination is by binding factors?
I always thought homosexuality was hormonal, a type of brain-hermaphrodism like transgender and psuedo-hermaphrodites since we all start off in the same place anatomically inbetween, I assumed we must also start off in the same place in the brain inbetween male & female sexuality & gender identity.

I would suggest you pause and look up the terms for this video. I will attempt to simplify in the next videos.

He doesn't even understand population genetics. He really is clueless.
