This perfectly illustrates how the woke operate.
In pic 1 @zaelefty says, correctly, that there's *2 SEXES* in most complex multicellular life.
@Hood_Biologist responds by saying there's 6 common and 4 rare *SEX KARYOTYPES*
*SEXES* on one hand *SEX KARYOTYPES* on the other

Did you catch that?
@zaelefty makes a comment about *SEX* and @Hood_Biologist responds by making a claim about *SEX KARYOPTYPES*
@Hood_Biologist is using linguistic sleight-of-hand here, and I am going to show you how it works so you can spot it next time.

I'll explain the difference between *sex* and *sex Karyoptypes* and then we'll see whats going on here.
Humans have reproductive cells, that is, the cells that are put to work in the process of reproducing. In Humans, there are two types of reproductive cell: Sperm and Eggs.

Sperm are the Males reproductive cells, Eggs are female reproductive cells.
Humans also have male and female genitalia which are part and parcel of the reproductive equipment that human beings have.
@zaelefty goes into great detail about that here: https://twitter.com/zaelefty/status/1333675023857561600?s=20

So what is a *sex karyotype*?
The Karyoptype has to do with chromosomes. That is, what chromosome combination a particular human has.
So @Hood_Biologist gives us a list of a number of possible chromosome combinations, which you can see here:

And here's where the sleight-of-hand occurs.
Chromosomes contain genetic material (DNA) which make us what we are. An inexact analogy would be to say DNA is the blue print for everything in your body: limbs, organs, bones, skin, hair, and the cells that make them up...

and *almost always* a person with XX Chromosomes produces eggs and has female genitals, and a person with XY Chromosomes produces sperm and has male genitals.
This is because *ALMOST* always the genetic material for making male genitals and gametes is on the Y Chromosome

And, in the vast majority of cases, human being have two chromosomes. This means that in the vast majority of cases human beings are either XX and female, or XY and male.
again *ALMOST ALL CASES*
that *ALMOST* is where the sleight of hand occurs...

There are 2 types of exceptions @Hood_Biologist
uses to make the sleight-of-hand work, one is about chromosome type, the other is about chromosome number.
The first is that sometimes a person can have more than two chromosomes. For example, instead of XX a woman might be XXX

The second type of exception is that sometimes the genetic material for making male genitals and gametes can come off the Y chromosome and end up on the X chromosome.
This means that the information for making male organs and gametes can end up on an X Chromosome...

You can think of Chromosomes like files with pages of genetic information. The file marked 'Y' almost always has the information for making male organs and gametes. But sometimes those pages 'fall out' of the 'Y' file and end up in the 'X' file.
It's rare, but it happens

What this means is that there are various accidents which occur that fall outside our usual rule of "Men have XY chromosomes and Women have XX chromosomes"
but those accidents do not mean there are more than two sexes. And that is the point...

What hood biologist is doing it by pretending that each karyotype, each constitutes a different sex, but they don't
For example, a person who has female gametes and sex organs does not stop being female just because she is XXX instead of XX.

The game @hood_biologist is playing to to pretend that *sex* refers to chromosome type, when in fact it refers to gametes (whether you produce sperm or eggs) and sex organs.
It is true that the Chromosome combination one has usually predicts what sex they are...

But there are exceptions. A man with male genitals who produces sperm may, in very rare cases, have an XX chromosome set (if the genetic material for making male organs and gametes comes off a Y chromosome and onto an X chromosome)

So while the Chromosome type is indicative of what sex a person is, *MOST OF THE TIME,* there are exceptions. Chromosomes should not be confused with sex.
Chromosomes are not sex for the same reason the cook book is not the cake.

Sex is about what reproductive cells a person produces, what genitals they have, and what their reproductive function is. Appealing to obscure and rare chromosome anomalies to try to confuse people about biology so you can switch the definitions on them is immoral and unfair.

To recap, sex is about the gametes (Reproductive cells, sperm or egg) a person has, and there are 2 sexes; and usually, but not always, sex tracks closely with the Chromosome combination a person has.
