Your child at first by the father\'s sperm and a combination consisting of an egg fertilized egg of the mother, after repeated differentiation, can gradually become similar to the development of your fetus.
Is similar to the children and their parents pass genes to the fertilized egg\'s sake. Therefore, children build height, body size and weight, colour of the level of depth, size of the eyes, nose, ears, teeth of the shape of thin dense, amount of hair, intelligence is good or bad, the length of life, also have blood pressure, blood group, red blood cell count, some diseases and resistance, and so on, are associated with genetic parents. For example, in the parents \' genes have \"high\" symbol, children who are born later tend to grow into a tall, while children build the shorter.
Human fat, thin, also has a genetic factor, often see some \"drinking cold water are the meat\", and some people anyway to eat also grow fatter. However, a class such as height, weight, life, mental hereditary, both depend on the genetic characteristics of the parents, and under the influence of environmental factors, which are referred to in genetics multifactorial inheritance.
So under the same parent children, those from the nutrient-rich, focusing on physical exercise of children, physical fitness is better.
