male
Theyre female because males have XY.
Xy=male xx=female
XX for female, XY for male
Female XX Male XY
XY relates to genetics, not science fiction, or fantasy. Basically if you are XY, it means you are male, whereas if you are XX you are female. Jacki.
The genotype for a male is XY. A female is XX. The 23rd homologous pair is the sex gene that determines this.
A female is an XX. However, during development one of the X chromosomes is deactivated and is called a Barr body.Human females have XX sex chromosomes. A male has XY chromosomes. The Y chromosome is very small and contains only genes that make a male a male.
XY=male; XX=female…
XX is for Female and XY is for Male.
Chromosomes effect the body by telling it if you will be male of female. XX is the chromosome for a female and XY is for male.
The sex chromosomes. XX is female and XY is male.
There are 22 autosomal chromosomes and 2 sex chromosomes in humans. In all the other chromosomes, the homologous pairs match up genetic loci. However, in human sex chromosomes the X and Y chromosome are different (with the X chromosome being much larger and the Y chromosome carrying genes that cause "maleness"). Someone with an X and a Y chromosome is a male because he has a Y chromosome that carries the genes that code for "maleness". Females "lack" this Y chromosome, and thus show characteristic female phenotypes.
