CHAPTER OUTLINE
... Out of 23 pairs of chromosomes, 22 are called autosomes and one pair is the sex chromosomes, so named because they differ between the sexes. In humans, males have the sex chromosomes X and Y, and females have two X chromosomes. Traits controlled by genes on the sex chromosomes are said to be sex-lin ...
