Many organisms have been reported to choose their mates in order to increase the heterozygosity of their offspring by avoiding mating with relatives or homozygous individuals. Most previous studies using Drosophila melanogaster have used artificial chromosomes or extreme inbreeding treatments, situations unlikely to be matched in nature. Additionally, few studies have examined the interaction between female inbreeding status and her choice of mate. Using females and males from populations that had experienced either random mating or one generation of sib-sib inbreeding, we measured the preferences of females for males. Our results indicate that outbred males were chosen more often than inbred males and that this preference may be more pronounced in outbred females than in inbred ones.

近亲繁殖对两种果蝇雌性配偶选择的影响

据报道,许多生物选择配偶是为了通过避免与亲属或纯合个体交配来增加后代的杂合性。大多数以前使用黑腹果蝇的研究都使用了人工染色体或极端近亲繁殖处理,这种情况在自然界中不太可能匹配。此外,很少有研究检查女性近亲繁殖状态与其配偶选择之间的相互作用。我们使用来自经历过随机交配或一代同胞近交的种群的雌性和雄性,测量雌性对雄性的偏好。我们的结果表明远交雄性比近交雄性更常被选择,而且这种偏好在远交雌性中可能比近交中更明显。
