Natural Selection on Mate Recognition in Field Populations of Drosophila serrata

配偶识别的自然选择被认为在物种形成过程中起着重要作用。 密切相关的物种在其分布重叠的地区，被称为生殖特征位移，更强的交配歧视，表明配偶识别已被自然选择加强。 在与同源物D同时出现的区域，果蝇serrata显示出生殖特征置换。Birchii。 利用分子和数量遗传学技术相结合，我将调查如何在自然种群的D。锯齿状。 具体来说，自然选择在产生这种模式中所起的作用将被评估。

Natural selection on mate recognition is thought to play an important role in the process of speciation. Stronger mating discrimination between closely related species in areas where their distributions overlap, referred to as reproductive character displacement, suggests that mate recognition has been reinforced by natural selection. Drosophila serrata displays reproductive character displacement in areas where it occurs alongside the congener D. birchii. Using a combination of molecular and quantitative genetic techniques I will investigate how reproductive character displacement has evolved in natural populations of D. serrata. Specifically, the role that natural selection has played in generating this pattern will be evaluated.
