Whilst I agree with your sentiment, I think you have some of this the wrong way round.
Female is XX
Male is XY
Yes, I know all about DSDs, however, they are differences or disorders of sexual development, where the normal pathway has gone wrong
A transman can't become biologically male, because they cannot change their second X chromosome into a Y chromosome.
A transwoman can't become biologically female, because they cannot change their Y chromosome into a second X chromosome.
Now, I'm just generally replying to the thread.
XX female, XY male is why red colourblindness is so much more prevalent in males (1 in 50) than in females (1 in 200).
The main gene for the red cones (light receptors on the back of the eye that can see red light) is located on the X chromosome.
Women have two copies of this gene, one on each of their X chromosomes. If they have one 'dodgy' copy of the gene, their second copy allows them to still make the red sensing cells, and they can see red.
If a woman has two 'dodgy' versions of the gene, she will be red colourblind. This is much less likely to happen, and would require to have a red colourblind father, and either a red colourblind mother, or a mother who was a carrier of red colourblindness.
HOWEVER,
Males only have one copy of the X chromosome. Therefore, if they have one 'dodgy' copy of the gene, they do NOT have a spare copy, because the Y chromosome is small and does not contain a copy of the gene. Therefore, they only need to have one parent who passes on the 'dodgy' gene(their mother).
Interestingly, a father can never pass his colourblindness onto his son, because he only passes on his Y chromosome to his son.
A colourblind father can pass his colourblindness on to his grandson, via his daughter being a carrier.
This was my situation. There was a 50:50 chance that my son would be red colourblind. My father is red colourblind, therefore I must have recieved his 'dodgy-gene X' from him, and a second, 'normal-gene X' from my mother, which allowed me to see red.
When it came to having my son, he recieved his Y chromosome from my DH, and an X from me. 50:50 whether it was the dodgy or normal version.
For my DD, it's 50:50 whether she is a carrier, or not.
So actually,
Being female or male does affect people, even in ways you might not have thought of.
(The other types of colourblindness are not sex linked, the genes for seeing green and blue are not on the sex chromosomes).
