Great video at the OP's link.
The video is totally and completely wrong because the forensic lab may not be able to tell if DNA is male or female.
XX is female and XY is male, but what is XXY or ZYY, or the half dozen other possible but rare combinations?
There there is the fact that even if one has male or female DNA, that does not mean the person matches that DNA.
DNA is a blueprint that normally gets followed, but due to things like viruses, hormones in food, etc., you can turn out totally different than your DNA.
So a DNA test does not at all have to indicate how one has turned out.
There are just too many other factors.
