基因的直线排列本讲座的第五篇文章中曾提及香豌豆与玉米的连锁遗传并且从玉米染色体的局部交换上面还提供了连锁遗传细胞学上的根据。实际上,有关连锁遗传解释最早的线索还是来自果蝇遗传的研究。应该说伴性遗传问题的提出是第一次具体地把遗传因子安插到一个固定的染色体上面。没有这样一个事实作为理论基础,想把 The Straight Line of Genes The fifth article in this lecture referred to the linkage inheritance of sweet pea to maize and provided the genetic basis of the linkage inheritance from the local exchange of maize chromosomes. In fact, the earliest clues to genetic explanation for linkage are derived from Drosophila genetic studies. It should be said that the problem of sex-linked genetics is the first time that genetic factors are specifically inserted onto a fixed chromosome. There is no such fact as a theoretical basis, want to put
