Little is known of the evolutionary forces that maintain same-sex sexual behavior (SSB) in natural populations, despite its common occurrence. We will use 192 inbred lines of Drosophila melanogaster that have been derived from a natural population in North Carolina, to test the two main genetic models of SSB: overdominance and sexual antagonism. We will screen all inbred lines for male-male SSB to identify those containing high levels of SSB and those containing low levels of SSB. The top and bottom 5 lines will subsequently be used in crossing experiments to identify genetic components contributing to SSB. The chromosomal location, dominance relationships and correlations with fitness make clear predictions favouring the different genetic models of SSB, and by quantifying these, we will assess the likelihood that SSB is maintained under either model. The results will provide much-needed data on the genetic architecture of SSB, which is a prominent, yet often overlooked, source of variation in mating behaviour in natural populations.

尽管同性性行为（SSB）在自然种群中很常见，但人们对维持这种行为的进化力量知之甚少。我们将使用来自北卡罗莱纳州自然种群的192个黑腹果蝇自交系来测试SSB的两种主要遗传模型：显性和性拮抗。我们将对所有自交系进行雄性-雄性SSB筛选，以确定SSB含量高的和SSB含量低的。顶部和底部的5行随后将用于杂交试验，以确定对SSB有贡献的遗传成分。染色体定位、显性关系和与适合度的相关性明确预测了SSB的不同遗传模型，通过量化这些模型，我们将评估在任何一种模型下SSB维持的可能性。这一结果将为SSB的遗传结构提供急需的数据，SSB是自然种群中交配行为变化的一个突出但经常被忽视的来源。
