Summary Introduction

The human genome contains 46 chromosomes (23 pairs) and they carry genetic information. The human genome contains 22 pairs of autosomes and one pair of sex chromosomes (X and Y chromosomes). Chromosomes contain genes, which are the basic unit of genetic information. Alleles are known as different versions of a gene. In the diploid cell, two different alleles of a gene can present in a given locus on the pair of homologous chromosomes.
