Genetic Basis of Cancer
Humans usually have 46 chromosomes, which are found in most cells in the body. Chromosomes come in pairs. One chromosome in each pair, one from each parent (biological mother and biological father). There are two types of chromosomes: autosomes and sex chromosomes. Humans have 44 autosomes and 2 sex chromosomes. Autosomes are virtually the same in men and women, while sex chromosomes determine whether humans are biologically male or female.
