We officially now have MALE, FEMALE and X

[I_am_not_mafia]

23rd Chromosome  

XX = Female
XY = Male

I understand that biology isn’t always that neat but pretending you’re something you’re not doesn’t make it so.

Male and female is more than just a different chromosome.

And most of that different chromosome isn't even concerned with sex differences.

How many times have you been concerned about someone else's chromosomes?

Also there are many, many people out there who have completely different chromosonal arrangements and you still see them as either male or female. The entire population can't be divided into XX or XY.
