Also, these traits are controlled and determined by different genes' expression such as aggressiveness and limit of patience. Some studies have proved the child's characters were decided by the dominance of Nature (heredity) over Nurture (experience). Firstly, identical twins that grew up together are considerably more alike psychologically than two people physically distinct (non-twin). Next, identical twins that grew up separately are more resembling mentally than fraternal twins that grew up together. Further, the biological siblings that grew up together are more similar psychologically than adoptive siblings. One conclusion can be deduced, these comparisons show that the more these two people are genetically resemble, the more they share the similar characters. For this reason, parents are accountable for children's intelligence and personalities, because each parent transmit 23 chromosomes to the child. As a result, your child is somewhat a reflection of you. For example, you can be extremely competent in English, but your child, on his side, is proficient in Spanish, since he was raised in Spain.
