Abstract
The chiasma map of D. melanogaster is inferred from the genetic map, giving correspondences between physical and genetic locations. Crossing-over is reduced near the centromere and telomeres. If chiasmata occur preferentially near the telomere they must be distal to genetic loci. A precept of Bridges and Morgan is discussed, which Drosophila genetics neglected but chromosome mapping in other organisms should follow.
摘要
黑腹果蝇的交叉图谱是从遗传图谱推导出来的，给出了物理位置和遗传位置之间的对应关系。着丝粒和端粒附近的交叉减少。如果交叉优先发生在端粒附近，那么它们必定位于基因座的远端。本文讨论了布里奇斯和摩根的一条规则，果蝇遗传学忽略了这条规则，但其他生物体的染色体图谱绘制应该遵循它。
