The term 'naturally inherent' can be summarized by the word 'INBRED, ' which is a six-letter word. Inbreeding is the practice of mating closely related individuals, such as siblings or cousins, in order to maintain certain characteristics within a population. This practice has been used for centuries in animal husbandry and plant breeding, and is still used today in some cases. In humans, it is generally frowned upon due to the potential for increased risk of genetic disorders.
