从遗传学角度上讲，人脑的发育属多基因遗传（用各种方法计算的遗传度为５０％～７０％），受基因和环境的共同作用，脑的结构和功能同基因的质量直接相关，但也受环境因素的影响，即相同遗传基础可因不同的环境因素产生明显的差异。脑的发育是决定脑的基因逐步表达的过程... From a genetic point of view, the development of the human brain is a multi-gene inheritance (genetic degrees calculated by various methods of 50% to 70%), by the gene and the environment together, the structure and function of the brain directly with the quality of the gene But also affected by environmental factors, that is, the same genetic basis may cause obvious differences due to different environmental factors. Brain development is the process of determining the brain’s progressive expression of genes ...
