野生数量遗传学研究集中在一个子集的性状(主要是形态和生活史),与其他人,如行为,受到较少的关注。这是因为获得足够的数据是具有挑战性的,特别是对于涉及个体之间互动的行为。在这里,我们探讨了一种间接的方法,试点调查的作用,遗传差异产生的变化,在父母的照顾。双亲遗传效应对后代表现的影响可能是由双亲间的遗传变异引起的。因此,我们使用动物模型来预测羔羊生长的母体繁殖值,并使用这些预测来选择雌性进行现场观察,记录母体和羔羊的行为。更高的预测母畜繁殖值羔羊生长与更大的哺乳成功,但没有与任何其他措施的哺乳行为。虽然我们的工作不能明确估计所涉及的特定性状的遗传基础,但它确实提供了一种假设生成和改进的策略,我们希望可以用来证明验证性研究所需的数据收集成本。在这里,研究结果表明,行为遗传变异参与产生母系遗传效应对羔羊生长在Soay羊。虽然重要的警告和注意事项适用,我们的方法可能会扩展的能力,启动更多的遗传调查难以研究的行为和社会互动的自然群体。
Wild quantitative genetic studies have focused on a subset of traits (largely morphological and life history), with others, such as behaviors, receiving much less attention. This is because it is challenging to obtain sufficient data, particularly for behaviors involving interactions between individuals. Here, we explore an indirect approach for pilot investigations of the role of genetic differences in generating variation in parental care. Variation in parental genetic effects for offspring performance is expected to arise from among-parent genetic variation in parental care. Therefore, we used the animal model to predict maternal breeding values for lamb growth and used these predictions to select females for field observation, where maternal and lamb behaviors were recorded. Higher predicted maternal breeding value for lamb growth was associated with greater suckling success, but not with any other measures of suckling behavior. Though our work cannot explicitly estimate the genetic basis of the specific traits involved, it does provide a strategy for hypothesis generation and refinement that we hope could be used to justify data collection costs needed for confirmatory studies. Here, results suggest that behavioral genetic variation is involved in generating maternal genetic effects on lamb growth in Soay sheep. Though important caveats and cautions apply, our approach may extend the ability to initiate more genetic investigations of difficult-to-study behaviors and social interactions in natural populations.
