How does a person’s heredity depend on his parents?

How are genetic factors help define an individual?
Genetic factors clearly help to define us as individuals and our intrinsic susceptibility to toxicity from chemicals or pharmaceutical agents ( Chang et al., 2009 ). The impact of genetic factors in this area will be further modified by gender, age (life stage), and nutritional status.
How does heredity influence body size and fitness?
