Supplementary Figure 1. Experimental tank used in affiliation trials to assess mate preferences of S. alburnoides females towards AA, QQ and PP males. The pentagonal area at the center corresponds to the neutral “no choice” zone. The proportion of time spent by each female in the dashed areas of each branch was used to index its preference towards each male genomotype, isolated in the peripheral compartments by perforated transparent acrylic plates.

补充图1。本实验水槽用于亲和性试验，以评估S. alburnoides雌鱼对AA、QQ及PP型雄鱼的择偶偏好。水槽中央的五边形区域为中性‘无选择’区间。每尾雌鱼在各分支的虚线区域内停留的时长占比，被用作衡量其对各雄鱼基因组型偏好的量化指标；各雄鱼通过穿孔透明亚克力板被隔离于对应的外围隔间中。
