Sex chromosomes are the chromosomes involved in determining the sex of an organism (male or female).
It occurs in pairs, in somatic cells and singly in sex cells (gametes)
- A somatic cell contains a genome comprised of paired chromosomes- the autosomes and sex chromosomes. In humans there are 2 forms of chromosomes; X chromosomes and Y chromosome.
- A pair of X and Y chromosomes result in a male while X and X result in a female. This system is applicable in both animals and humans.
Your picture helps me understand your topic. A lot of people don't know which sex XX and XY is. I don't think you down a reflection.
