Ahhahahahhahah you appeal to biology while proving your ignorance of biology, please do double down so we can all point and laugh some more
And you appeal to your narrative, and engage in the pointless tactic of shaming. You Drinkypoo, are allowed to have your narrative, and if you want to believe you are a horse, or a seal, or anything that gives you purpose, but you are none of those, and trying to claim I am clueless about DNA, merely points out that you are perhaps not the juggernaught of knowledge you like to portray yourself as.
It really isn't rocket science, to use another hackneyed term, but it boils down to this as a nickel tour:
DNA is a polymer (of all things) two of them that wrap around each other. This is the famed double helix structure. The polymers have repeating units called nucleotides. These are composed of a number of things like lipids (fatty material) sugar groups (polysaccharides) like ribose, and phosphates. Both strands of the double helix contain the same information. In eukaryotic cells, the DNA information is organized in structures called chromosomes.
This just touches the surface, so I'll go to male vs female differences at the chromosome.
When we look at the sexual differences, there is a very distinct difference between males and females. The top level definition is that Males have two sex based chromosomes, named X, and Y. Females have two sex based chromosomes, both are X.
The Y chromosomes contain what is called the SYR gene, which the gene that controls development of the testes.
DNA is not perfect, as plenty of mutations can occur. When they involve the X and Y Chromosomes I group them under intersex. Some are strange indeed. There is hermaphroditism, where the genes are mixed up. and sometimes becomes the SYR gene migrates to places it normally wouldn't.
There is also a case with women, where all external appearances appear normal, often tall, slender and beautiful, but no internal sexual organs exist.
But the existence of outliers does not alter the fact that a fully transitioned sex swap, where a normal male or female transgender person takes puberty blockers, injections of hormones, has breasts or penis and testicles amputated, and artificial genitals surgically constructed, and can look for all the world like the opposite sex, a DNA test that shows the X and Y Chromosomes show that person to be unambiguously male, and two X Chromosomes presented show that the person is unambiguously female.
This has nothing to do with politics. DNA is DNA, we might as well have a vote on the speed of light, or Ohm's law, or the energy retention or rejection characteristics of an atmosphere controlled by the gaseous components of that atmosphere.
And it is a particularly odd hill to choose to die on. Denial of DNA is anti-science. Just like vaccine denial is anti-science, especially with the new MRna vaccines. Or that living things do not evolve, or they the earth was created around 6000 years ago. If we wish to enter the political spectrum, what needs attention is hatred of transgender people. That is a political thing.
Compassion and acceptance of different people is key. Laugh away.
