Summary Introduction

Every species contains a particular number of chromosomes. For example, humans have 46 chromosomes (23 pairs of homologous chromosomes) and mosquitoes have total 6 chromosomes (3 pairs). Each chromosome has a specific structure and arrangement of genes with a precise sequence. Any alteration in the number or structure of the chromosome is known as a chromosomal abnormality.
