行为生态学行为生态学
进化生物学进化生物学

背景情况:

遗传变异推动了适应环境变化的过程.
复杂的行为往往是多个基因相互作用的结果.
染色体逆转抑制了重组,将遗传变异联系起来,并可能影响多个特征 (多重变异).

研究的目的:

为了研究反向In(2L) t对Drosophila melanogaster.各种行为的影响.
要确定这些行为效应是否对环境敏感 (例如温度) 和性别特定.

主要方法:

检查了不同In(2L) t基因型的的活动,食和惊吓诱导的行为.
评估不同温度和性别的行为反应.

主要成果:

在2L中同卵性的睡眠频率有所减少.
这些花了更多的时间远离食物来源,并表现出长时间的惊反应.
In(2L) t对行为的影响通常是性别特异的,并且在测试温度中一致.

结论:

染色体逆转,如In(2L) t,在各种行为方面发挥着调节作用.
研究结果表明,逆转可以影响种群的进化和分布.

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

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...
