Abstract

Chiasma frequency was measured in male mice of three outbred lines: FZt:DU (control); DU:6, selected for increased body weight; and DU:C, selected for high fertility. Chiasma frequency was seen to increase in the high body weight line, but decrease in the high fertility line. In both selected lines the intragroup variance in chiasma frequency increased while in DU:C the intracell variance was lower than in the control.

摘要

在三个远交系的雄性小鼠中测量了交叉频率

FZt:DU（对照）；DU:6，选择用于增加体重；和 DU:C，选择用于高繁殖力。在高体重系中观察到交叉频率增加，但在高繁殖力系中降低。在两个选择系中，交叉频率的组内方差增加，而在 DU:C 中，细胞内方差低于对照。
