- 昆虫病毒学 昆虫病毒学
- 蛋白质组学是指蛋白质组学.
背景情况:
- 蜜蜂群体的健康依赖于女王的繁殖成功,后者受到病毒感染的威胁.
- 跨代免疫启动 (TGIP) 涉及女王将免疫防御传递给后代,潜在地提高殖民地对病毒的抵抗力.
- 关于TGIP在蜜蜂中的病毒及其对蛋成分的影响的知识有限.
研究的目的:

01:21Frequency-dependent Selection
21.7K
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.

02:27Background and Environment Affect Phenotype
6.4K
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...

Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.
