概括
母体大小不会影响寄生虫黄蜂Gelis agilis的后代大小. 后代的大小主要取决于宿主的大小,而不是由母黄蜂的大小或资源供应决定.
科学领域:
- 进化生物学是进化的生物学.
- 昆虫生态 昆虫生态
- 现型性可塑性 现型性可塑性
背景情况:
- 动物的表型变异受遗传学和父母资源的影响.
- 父母的照顾有很大的不同,昆虫往往缺乏这种照顾,但有些昆虫可以增强后代的生长.
- 寄生虫黄蜂使用母体因素来提高宿主质量,但母体大小的作用尚不清楚.
研究的目的:
- 调查寄生虫黄蜂Gelis agilis母体大小和后代发育之间的关系.
- 为了确定母体大小是否影响后代的大小和发育时间,独立于宿主质量.
主要方法:
- 在实验中改变了母体大小 (小与大) 和宿主大小 (Cotesia glomerata的子).
- 测量了Gelis agilis的后代体型和发育时间.
- 分析了母体大小,宿主大小和后代特征之间的相关性.
主要成果:
- 在Gelis agilis中,后代的大小与宿主大小有很强的相关性,无论母体大小如何.
- 对于给定的宿主大小,母体大小没有显著影响后代的大小.
- 提供的摘要中没有详细说明开发时间,但是在此类研究中,这是一个常见的指标.
结论:
- 主体质量是Gelis agilis中后代大小的主要决定因素.
- 在这种物种中,母体大小似乎没有在调节后代大小方面发挥重要作用.
- 研究结果表明,预先确定的宿主质量在很大程度上决定了后代的表型变异.

01:21Frequency-dependent Selection
21.8K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
