Chromosome Map. Our genetic information is stored in 23 pairs of chromosomes that vary widely in size and shape. The 23rd pair of chromosomes are two special chromosomes, X and Y, that determine our sex. Females have a pair of X chromosomes (46, XX), whereas males have one X and one Y chromosomes (46, XY).
