Is posible that the a human can carrie YY or YYY or YYX If this is not posible, then why is not I want a explanation?
The correct order is XY, where X represents the larger chromosome and Y represents the smaller, sex-determining chromosome.
Y chomozomes, I think. It says on Wikipedia.
The sex chromosomes of a man are XY (vs. XX for a woman).
The 23rd chromosome is the sex chromosome. It is either an X or Y (strictly male) chromosome. When the sperm and egg cells fuse, they combine into 46 chromosomes with either two X chromosomes or an XY pairing. If it is 2 X chromosomes, the zygote is a female. If it is an XY pairing, the zygote is a male.
the male chromosome is XY the female chromosome is XX
The correct order is XY, where X represents the larger chromosome and Y represents the smaller, sex-determining chromosome.
The male chromosome
The male human is represented by a sex chromosome consisting of one X chromosome and one Y chromosome (XY).
A boy has one X chromosome from the mother and one Y chromosome from the father, making his chromosome pair for gender determination XY.
male sex chromosome

XY
Xy chromosome
XY
A mother needs to contribute an X chromosome to her child for them to be male. The father contributes a Y chromosome, resulting in an XY chromosome pair which determines a male child.
XY = Male XX = Female
It is on the X Chromosome (male have XY chromosome Females have XX Chromosome)
