Abstract
In the dynamics of the survival of chromosomal polymorphism selection may be operating at the genic level, at the chromosomal level or at the supergene level. Tests designed to distinguish between these levels were run on Drosophila pseudoobscura. There was no evidence for heterosis, a necessary requirement for gene-determined chromosomal polymorphism A strong chromosmal selection was observed. No evidence was found for the presence within one locality of more than a single superallele for each supergene (equals gene order). These results are compared to those found by others.
摘要
在染色体多态性生存的动态过程中，选择可能在基因水平、染色体水平或超基因水平上起作用。针对果蝇进行了旨在区分这些水平的测试。没有证据表明存在杂种优势，而杂种优势是基因决定的染色体多态性的必要条件。观察到强烈的染色体选择。没有发现证据表明在一个局部区域内每个超基因（等同于基因顺序）存在多个以上的超等位基因。将这些结果与其他人的结果进行了比较。
