概括
雄性果根据雌性交配状态调整他们的求爱仪式. 雄性更频繁地与交配的雌性重新开始求爱,这可能导致抑制,与不成熟的雌性不同.

- 伦理学 伦理学 伦理学
背景情况:
- 草的求爱是一种固定的行动模式,对昆虫的交配至关重要.
- 行为可塑性允许雄性适应求爱参数 (例如,歌曲) 并在拒绝后抑制求爱.
- 求爱学习的神经机制已知,但男性测序与女性线索的相互作用仍然不清楚.

The Ratio of X Chromosome to Autosomes
9.4K
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...

Mate Choice

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
