A chromosome first termed by W. Waldare, in Greek means colored body because it appears colored under the microscope in a specific stain. It is a chemical long chain molecule in each & every cell of the living being. This is so much compact that several meter long chain occupies a very little or say negligible space. It can not be seen with naked eyes but still performs tasks in the body those are more than significant and indispensable to continue life. This so called tiny molecule is responsible for the morphology (External appearance viz.: complexion, body structure, height etc.) of a creature and too it decides the anatomy of an organism. The sex chromosomes named X and Y are mainly responsible for whether what would be the result of a fusion (copulation) a male child or a female (as depicted in the figure.)In human beings 46 chromosomes are found and any abnormal increase or decrease in the chromosome number may result into chromosomal aberration and the repercussions may be a being with contingent disease which may be fatal too.
