Heritability is properly defined as the “sum of characteristics and potential genetically derived from one's ancestors” (Merriam-Webster Dictionary, 2011). At conception, each embryo is given a portion of genetics from each parent or donor's gene pool, which allows the process to create another human being; that we call a child. Genetics tells us what kind of traits the embryo will inherit through the genes of the parent or donor. In any case, there is a possibility that the embryo could get good genes, or bad genes, or both from the parent's or donor's genes. Therefore, when both genes combine, they become traits of a person. When the fetus is born, it will be exposed to all elements of life until the person's death. In return, due to this lifetime exposure, this process could influence a person's behavior, regardless of their genes. Genetics in themselves do not control a person's behavior, but when you add hormone to the consideration you come to another factor to consider. When considering a person's hormones as a factor, this type of problem can contribute to the person's behavioral problems. However, according to researchers, human hormones are now considered a powerful drug that the body produces from the endocrine glands. However, when you put both a person's gene and hormones together, it can affect the person's behavior. According to research, it is known that behavioral development begins at the moment of conception, after several studies have been conducted. When genes from both parents are passed on to the child, these genes can contribute to the child's intelligence, talents, behavior, and any other type of disorder. However, behavioral development can also be... middle of paper... It would not exist without the adrenal hormones produced by the body. However, according to researchers, healthy adrenal glands could lead to a healthier body. Both hereditary genes and hormones produced by the body can influence and influence a person's behavior. Therefore traits considered purely genetic can be highly heritable; while other traits can be influenced by surroundings, environment and behavior with low heritability. Many traits exist from a mixture of genetic and environmental problems. Inherited traits could be considered the foundation from which each person can build and shape their own distinctive personality. Hormones can be affected by diet, exercise and medications. Controlling and adapting to one's surroundings and environment allows each person to survive and be in control of their destiny.
