If memory of my biology classes serves me right;That logic would also indicate that part of the chromosomes in the female DNA are male from when they were created... One could argue the XY/XX paradox between dudes and the ladies.
The Y chromosome is constant, it cannot merge.
Whereas the X (female) chromosome is forever merging.
A women chromosome doesn't merge with a male chromosome.
When a female is born, she will 'take' chromosome from her mother, her mother's mother and from her father's mother.
Come to think abt it, males born from the same womb/mother but from different fathers can't be technically brothers....now this will mindfvck some.
