概括
在科普的灰色树中,amplexus或雄性青紧握的行为迅速增加了丸激素和雌激素. 这种行为会激活生殖激素轴,但不会激活压力激素轴.
科学领域:
- 行为内分泌学 行为内分泌学
- 动物行为 动物行为
- 生殖生物学 生殖生物学
背景情况:
- 荷尔蒙显著影响行为,但研究量化特定行为导致的荷尔蒙变化并不常见.
- 雄性青在繁殖之前表现出,野生种群在的雄性中显示出更高的类固醇激素水平.
- 青的性行为提供了一个模型,以实验性地将一个离散的行为与其荷尔蒙结果联系起来.
研究的目的:
- 为了实验测试,如果amplexus的行为行为行为导致男性科普的灰色树 (Hyla chrysoscelis) 的循环激素增加.
- 为了研究安普莱克斯对,雌激素和皮质水平的影响.
主要方法:
- 建立了三组治疗组:AMPLEXUS诱导的雄性,AMPLEXUS终止的雄性和对照雄性.
- 激素水平 (,雌激醇,皮质) 在90分钟后被测量.
- 科普的灰色树 (Hyla chrysoscelis) 被用于这个实验.
主要成果:
- 与其他两组相比,和雌激素水平在带诱导组显著更高.
- 在治疗组之间没有观察到皮质水平的显著差异.
- 结果表明,快速的荷尔蒙反应对行为行为.
结论:
- 广的行为行为迅速激活了下丘脑-垂体-腺轴,导致生殖激素的增加.
- 脑下垂体 - 脑下垂体 - 内脏轴 (参与应激反应) 没有受到安普莱克斯的影响.
- 这项研究为青的行为诱导的荷尔蒙变化提供了实验证据.

02:27Background and Environment Affect Phenotype
7.4K
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...

02:45The 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...
