Genetics is a word commonly used when someone is referring to genes, biological inheritance, or even the genetic codes known as deoxyribonucleic acid (DNA).

Some of us might not even be aware that we are actually dealing with genetics when we “conveniently” blame the presence of genes in our body or the genes we got from our parents when we are faced with issues such as obesity, intelligence quotient (IQ), or even our physical appearance.
