LECTURE 1 Human Chromosomes Human Karyotype
... The packaging of DNA into chromosomes involves several orders of DNA coiling and folding. The normal human karyotype is made up of 46 chromosomes consisting of 22 pairs of autosomes and a pair of sex chromosomes, XX in the female, and XY in the male. Each chromosome consists of a short (p) and ...
