摘要
本文详细介绍了生物的变异及其机制。生物的变异包括遗传变异和不遗传变异,遗传变异是由于遗传物质的变化而引起的。在细胞分裂的过程中,遗传物质发生重组产生变异;另外,生物体内外因素会影响遗传物质发生改变,从而产生变异。
Biomutation and its function were introduced specifically in this article.Biomutation includes hereditary biomutation and non-hereditary biomutation,and hereditary biomutation is caused by the change of hereditary substance.During the process of cell division,regroup of hereditary substance could lead to mutation;otherwise factor from organism and environment could affect the change of hereditary substance and mutation would be the result of the change.
