埋葬甲虫Nicrophorus vespilloides的育儿是复杂的，而且不寻常的是，父母的性别和数量是灵活的。这种灵活性预计将涉及在双亲条件下两性的特殊行为。在这里，我们表明，无论父母的性别或数量如何，后代都表现得同样好。比较转录组，我们发现一个很大程度上重叠的差异表达的基因在单亲和双亲女性和单亲男性，包括卵黄蛋白原，与生殖，外卖，影响性别特异性交配和喂养行为。双亲雄性动物的基因表达与无照料状态下的基因表达相似。因此，在N. vespilloides描述的是家庭的社会组织，而不是直接养育子女的个体的数量。没有专业化;相反，在双亲家庭中，男性父母的直接照顾似乎有限，女性的行为没有改变。这会导致强烈的性冲突。埋葬甲虫表现出灵活的育儿行为。在这里，作者表明，无论父母的性别或数量如何，后代的表现都同样良好，并在单亲和双亲女性以及单亲男性中发现了相似的基因表达谱，这表明养育子女没有专业化。
Parenting in the burying beetle Nicrophorus vespilloides is complex and, unusually, the sex and number of parents that can be present is flexible. Such flexibility is expected to involve specialized behaviour by the two sexes under biparental conditions. Here, we show that offspring fare equally well regardless of the sex or number of parents present. Comparing transcriptomes, we find a largely overlapping set of differentially expressed genes in both uniparental and biparental females and in uniparental males including vitellogenin, associated with reproduction, and takeout, influencing sex-specific mating and feeding behaviour. Gene expression in biparental males is similar to that in non-caring states. Thus, being ‘biparental’ in N. vespilloides describes the family social organization rather than the number of directly parenting individuals. There was no specialization; instead, in biparental families, direct male parental care appears to be limited with female behaviour unchanged. This should lead to strong sexual conflict. The burying beetle shows flexible parenting behaviour. Here, the authors show that offspring fare equally well regardless of the sex or number of parents present and find similar gene expression profiles in uniparental and biparental females and in uniparental males, which suggests no specialization in parenting.
