查询词典 sperm whaling

The researchers designed an experiment to test three possibilities: that males establish social dominance by mounting other males, that males who mount other males gain practice for later sexual encounters with females, and finally, that mounting males transfer sperm onto the other males, who then inadvertently inseminate a female with it later on.

研究人员设计了一个实验，测试雄性攀爬到其他同性身上的三种可能性：一、为了确立自己的社会主导地位；二、为以后同异性交配进行预演；三、排在雄性身上的精液可能会使稍后与之接触的异性意外受孕。

雄兽连续交配时，交配间隔、交配持续时间、每次爬跨持续时间、总爬跨持续时间、最后一次爬跨持续时间、射精持续时间等行为参数以及交配栓的重量均保持不变。表明雄兽具有恒定的交配投资模式，这种模式可能起因于该物种雄性之间激烈的精子竞争。

尤其是异配生殖如何由同配生殖转化而来，我们对此还懵懵懂懂。同配生殖是一种更为简单的结合形式，在此过程中，非常相似的生殖细胞不管三七二十一地就与不同的配子结合，都不分这些配子是"公"是"母"。
