A cryptic polymorphism found in natrual populations of Drosophila melanogaster has been examined in an artificial population maintained for over 200 generations. The polymorphism is selected because it is insensitive to the segregation distorter phenomenon, and it thereby largely preserves the Mendelian rules of segregation. Segregation distorter chromosomes and the cryptic polymorphism form part of a coadapted complex which is associated with linkage disequilibrium in natrual populations.
在一个维持了200多个世代的人工种群中,对在黑腹果蝇自然种群中发现的一种隐蔽多态性进行了研究。选择这种多态性是因为它对分离畸变现象不敏感,从而在很大程度上保留了孟德尔分离定律。分离畸变染色体和这种隐蔽多态性构成了一个协同适应复合体的一部分,该复合体与自然种群中的连锁不平衡有关。
