Hereditary factors in human growth (physical education)
Answers
Answer:
All traits depend both on genetic and environmental factors. Heredity and environment interact to produce their effects. This means that the way genes act depends on the environment in which they act. ... So in PKU, a single gene can dramatically affect behavior: it is clearly a genetically influenced process.

Answer:
Genetic factors play a central role in shaping human development and behavior. In most cases, the effects of these genetic factors are mediated by other genetic factors and by environmental factors as well. Indeed, some genetic differences may produce phenotypic effects only in specific “at-risk” environments
