Duration of ethanol (5 g/kg, orally) anesthesia was measured in male C57 B1/6 and white SHR (bred from Swiss) mice in three consecutive experiments with a 7-day interval between them. The number of short-sleep (SS) mice (duration of anesthesia was 30 min) and long-sleep (LS) mice (duration of anesthesia was over 120 min) in the selected groups decreased in the second and third experiments. This means that groups of SS and LS taken one and two weeks after the first selection for any experiment are not homogeneous because only in some animals the initial characteristics remain.
在雄性C57 B1/6和白色SHR（源自瑞士）小鼠中，连续进行了三次实验，每次实验间隔7天，测量经口给予乙醇（5 g/kg）后的麻醉持续时间。在第二次和第三次实验中，所选组中短睡眠（SS）小鼠（麻醉持续时间为30分钟）和长睡眠（LS）小鼠（麻醉持续时间超过120分钟）的数量减少。这意味着在任何实验的首次选择后1周和2周选取的SS和LS组并不同质，因为只有部分动物仍保留初始特征。
