It is known that male sex chromosomes are XY and female sex chromosomes are XX
Request: The origin of BL
Solution: Because: male sex chromosomes are XY (known)
Therefore: Assume that the male chromosomes are a plane rectangular coordinate system, and the two chromosomes X and Y are respectively
x-axis y-axis (equivalent substitution)
And according to the equivalent substitution formula, let X be positive (+) and Y be negative (-)
And because: the plane rectangular coordinate system has four quadrants, and the coordinates are (+, +) (-, +) (-, -) (+, -)
Therefore: Quadrants two (-, +) and four (+, -) are male tendencies.
The first (+, +) quadrant represents female tendencies
And according to the law of negative and positive, the three (-, -) quadrants are also female-biased
So: a man has a total of 1/2 masculine tendencies and 1/2 feminine tendencies.
Therefore: BL can be treated as a boy and a girl. As for who is a boy and who is a girl, it is related to the dominant gene and the recessive gene.
So: BL is the most normal thing in the world
Answer: Men are indeed the most suitable for BL!
