100 POINTS! CORRECT ANSWER GETS BRAINLIEST! Study the image of chromosomes in a human cell. Do the chromosomes in this image belong to a female or a male? Autosomes and Sex Chromosomes You may have noticed in the image of chromosomes in a human cell that all of the chromosome sets are labeled with a number except one set, which is labeled with X and Y. Together, chromosome pairs 1 through 22 makes up your autosomes, which are chromosomes that contain genes for characteristics not directly related to the sex of an organism. Most sexually reproducing species also have sex chromosomes that directly control the development of sexual characteristics. Humans have two very different sex chromosomes: X and Y. In all mammals, including humans, an organism's sex is primarily determined by the XY system. An organism with two X chromosomes is female. An organism with one X and one Y chromosome is male.
