前人为了探索遗传规律,付出了艰辛的劳动。十八世纪中叶奥国的孟德尔,以毕生的精力,用豌豆为试验材料,创立了分离规律和独立分配规律;十九世纪初美国的遗传学家用果绳作试验,以细胞学为基础,提出了连锁遗传理论,与孟德尔的二个遗传规律一起成为遗传学的三个基本规律。以后关于遗传学的研究逐渐兴起。我国在打倒“四人邦”以后,这方面的研究才蓬勃地发展起 In order to explore the genetic law, our predecessors have paid a lot of hard work. In the mid-18th century, Mendel in Austria made the law of separation and independent distribution with peas as his life-long energy. At the beginning of the nineteenth century, geneticists in the United States used the rope as a test. Based on cytology, Proposed the theory of chain inheritance, and Mendel’s two genetic laws together become the three basic laws of genetics. After the research on genetics gradually rise. After our country overthrew the “gang of four,” research in this field has only flourished
