Sex chromosomes and the work of mendel 

your chromosomes control wether your male or female

there are 23 pairs of chromosomes in every human body cell

the 23rd pair are your sex chromosomes and they are labelled XY 

Males have an X and Y chromosomes: XY  the Y chromosome causes male characteristics 

Female have two X shaped chromosomes: ** the lack of a Y chromosomes cause female characteristics 

like other characteristics sex is determined by a gene 

The Y chromosome carries a gene which makes an embryo develop into a male as it
