The main difference between genetics and hereditary lies in the fact that hereditary diseases have the potential of being carried from one generation to another whereas a genetic disease can either be hereditary or not, but there will always be a mutational change in the genome. Heredity refers to the genetic heritage passed down by our biological parents. That is why we look like them! More specifically, it is the transmission of traits from one generation to the next. These traits can be physical, such as eye colour, blood type or a disease, or behavioural. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
