How much of our behaviour is influenced by heredity (nature) and how much by environment (nurture)? How much percent.Give examples to support opinion.
Both are like the factors affecting human nature and psychology. Genes are herediatery traits responsible for carry information from the parent to the off-spring. I think both have affect on human beings not only from mental side but also have affect on physical appearance and characterstics. For example if a boy is born with white skin becoz his parents also own a white skin after a long time in sun due to incresed activity of melanocytes he will pave his way to black or brown skin. So, both nature and genes are responsible. Another example is that if a boy is born with humble nature, later happening bad instances in his life will make him cruel more than before.
