If chromosomes are the definitive method of determining biological sex, male and female, then how come so many people continue to say that it is actually genitalia that defines gender?
I'd say that due to malfunctions such as baby girls being born with a penis or baby boys being born with both a vagina and penis. This is a pretty poor method of determining which gender a person is assigned to at birth.
What is wrong with using chromosomes define biological sex? It's more indisputable.
Also, I ask this as a purely scientific question about biology.

What is the point of this thread? Anyone worth listening to would already assume chromosomes define actual biological sex, more so than physical genitalia. XX female, XY male.
Sex and gender are not the same thing dumbass.
It's also a gene on the Y chromosome that determines sex (SRY). Put that gene on an X chromosome and progeny that is genotypical female (XX) is born phenotypically male.
>>7891169
Is it possible to convert an XX to XY by adding SRY to one of the X chromosomes?
>>7891172
It's still XX, but the offspring is born male.

I'm in school studying Medicine.
The fact of the matter is that birth sex and gender is complicated, due to the complexity and intricacy of the human body and the various factors that work together to make someone male and female (such as chromosomes, prenatal hormones, genetics, genitalia, the brain, etc;)
The fact is that 99% of the time chromosomes xx and xy determine the sex of the baby, xx for female and xy for male respectively.
In 1% of cases, babies are born with chromosal disorders which lead to intersexuality, such as a boy being born xxy or xxxy, or a girl born with a y chromosome. And then there are cases where a child, in this case, a male is born with a hormonal problem, such as androgen insensitivity syndrome, which makes their brains and bodies unable to respond to testosterone, therefore leaving an unmasculinized, feminine brain and body; there are also syndromes/hormonal imbalances that cause girls to have masculinized brains and less feminine bodies -- and many of these girls suffer from autism; interestingly enough autism affects boys more than girls and there is some evidence that this is due to "overmasculinized brains".

And then we come down to prenatal hormones, which "Wash over" a baby's brain inside the mother's womb before birth. For boys they are exposed to testosterone and girls, estrogen. This permanently wires their brain into their gender identity, which coorelates to their birth sex.How much testosterone/estrogen exposure a baby receives will affect how masculine/feminine the boy/girl respectively, will behave and think later in life. If a girl acts like a tomboy and is pretty masculine and has boyish attributes, you can bet her brain was exposed to a lot of testosterone in the brain before birth. In men, there are feminine men, neural men and macho very masculine men, in the very macho men you can bet for sure their brains had a ton of testosterone exposure, more so than feminine and neutral acting men. This all comes down to something called digit ratio, and you can find out yourself how much test/estrogen you were biologically exposed to by measuring your index to ring finger.

Prenatal hormones also, obviously, affect gender identity, and if someone with a male or female chromosomes has their brain exposed to the opposite of their respective sex's intended hormones, then transsexuality occurs. They will have the gender identity that does not match their birth sex. It also determines sexual orientation.
https://en.wikipedia.org/wiki/Prenatal_hormones_and_sexual_orientation#Gender_dysphoria
https://en.wikipedia.org/wiki/Prenatal_hormones_and_sexual_orientation
Problems/errors with prenatal hormones can be caused by stress from the mother of some kind, certain medical drugs and other environmental factors as well as biological.
Finally there's the recent study that showed that men and women can have organs that are literally different genders, which makes for a unique perspective on what it means to be your birth sex if you have organs meant for the opposite sex.
>>7891213
tl;dr Prenatal hormone exposure, biological factors, genitalia, your organs, genetics all together determine what your sex is. The fact of the matter is that 99% of the time, chromosomes determine your biological sex, because what results is that the prenatal hormone exposure is normal, the genitalia is normal, the biological and genetic factors are normal and they all match up. 1% of the time, shit happens and shit goes wrong due to biological and/or environmental factors and thus makes determining someone's biological sex/gender complex; ie; they are a mix of male and female, and various factors determine how much male and female they are.
op is a faggot with homosomes instead of chromosomes

THERE'S A THING CALLED SEX AND GENDER, DON'T MIX THEM UP. ONE DEFINES BIOLOGY AND THE OTHER DEFINES IDENTITY.

An excellent informative series of posts that are at least sourced in some way and all you can do is act like a contrarian better than thou faggot spewing /pol/ level retardation. I almost forgot where I was, thanks for reminding me.

Well thanks. Well 4chan has a lot of retards who don't understand medicine/science, but there are some people who do and want to know it. Medicine is tough and stressful, but I always found it fascinating, hence why I got into it.
>What is wrong with using chromosomes define biological sex? It's more indisputable.
Because it's a pointless distinction.
The people who have a problem with some with xy chromosomes using the women's restroom aren't going to have any less of a problem with someone who has xx chromosomes but phenotypically male traits using the women's chromosomes.
No one is going to ask to see your karotype before you take a dump.

Protip: "Sex" and "gender" are not precisely defined concepts. There is a wide distribution of people on those metrics. Admittingly, the distribution is bimodal - aka most people tend to be reasonably accurately described as "male" and "female", but there are exceptions, including intersex, transex, transgender.
Chromosomes define sex
however it does not define gender
Sex does not equal gender.

>Life sucks, but why deny reality?
Because ignorance is bliss.

>Sex does not equal gender.
It does though. Otherwise what you're saying is that male and female characteristics are learned and not inherited, which is objectively wrong.
>>7893146
Then how come you lack all masculine characteristics.
>>7893146
No, Gender is a social construct
Sex is not.

I've seen a number of them with significant Narcissistic Personality Disorder, transgender is likely their easiest way to focus attention, though many seem perfectly normal. I think most cases are bullshit though.
