Differencebetween Genetics and GenomicsGeneticsisthe study of inheritable traits of living organisms and how these traits aretransmitted from one generation to another through Deoxyribonucleicacid (DNA) and Genomics in contrast,is the study of the complexity of the entirety of the organism’s several genes.In2002, WHO defined genetics as the study of single genes and their role in theway inheritable traits are passed on from generation to generations.
They explainedthat, genomics understudy all the genes of an organism taken together, plus allof the sequences and the information contained therein. The sequences and theinformation are referred to as genomes. Thescientific study of the effects that genes (known as the units of hereditary)have on the individual is what is referred to as genetics where as, genomicsincludes the study of how the genes within the genome interact with each otherand with the individual’s environment.Basically, genetics is concerned with inherited conditionssuch as cystic fibrosis, down syndrome, hemophilia, huntington’s disease,phenylketonuria (PKU) and sickle cell disease. These are inheritable traits.Genomics is concerned with complex disorders and diseases including asthma, diabetes,cancer, and heart diseases.
These diseases are caused by a combination ofgenetic and environmental factors, rather than just a mere single geneticdefect. Howgenomics fits into geneticsGenomics is the broaderumbrella encompassing genetics (Ballman, 2008). Though genetics scrutinizes thefunctioning and the composition of the single gene specifically, genomicsaddresses all genes and their inter-relationships in order to identify theircombined influence on the growth and entire development of the organism.Genomics therefore, involves identifying individual genes and placing them intosimilar roles through various different and sophisticated methods aiming athandling gene predictions regarding various genomes (entirety of an organism’s hereditaryinformation).
Genomics makes the study of single genes (genetics)possible.Generally, genomics is required to study or investigategenetic variation or the heredity of some traits (genetics) making use ofseveral technical and sophisticated methods. The study of several genes or genomeas a system makes genomics, a part of the biological systems.
