父母和子女的行为被认为是选择的代理人和目标。这可能会产生亲子共适应，在这种共适应中，父母和后代的行为在某种程度上变得遗传相关，从而增加了包容性适应性。交叉寄养已被用于研究亲子共适应，预测由非亲属抚养的后代，或父母抚养非亲属，应该承受适应成本。使用来自400多只部分杂交的蓝山雀（Cyanistes caeruleus）的长期数据，我们表明杂交和非杂交小鸡之间的质量或存活率没有差异。然而，先前的研究中，父母-后代共适应的证据是最强的，比较了来自完全杂交窝的小鸡与来自非杂交窝的小鸡。当亲子共适应作用于育雏水平时，部分交叉寄养实验预计不会显示共适应的证据。为了验证这一点，我们进行了一项额外的实验（163窝），其中离合器完全交叉，非交叉或部分交叉。与长期数据一致，尽管功效很高，但没有证据表明亲子共适应对后代适应性有影响。此外，没有证据表明对父母的适应性的影响，也没有证据表明兄弟姐妹的共同适应，虽然这些测试的力量更温和。
Parent and offspring behaviors are expected to act as both the agents and targets of selection. This may generate parent–offspring coadaptation in which parent and offspring behaviors become genetically correlated in a way that increases inclusive fitness. Cross‐fostering has been used to study parent–offspring coadaptation, with the prediction that offspring raised by non‐relatives, or parents raising non‐relatives, should suffer fitness costs. Using long‐term data from more than 400 partially crossed broods of blue tits (Cyanistes caeruleus), we show that there is no difference in mass or survival between crossed and non‐crossed chicks. However, previous studies for which the evidence for parent–offspring coadaptation is strongest compare chicks from fully crossed broods with those from non‐crossed broods. When parent–offspring coadaptation acts at the level of the brood then partial cross‐fostering experiments are not expected to show evidence of coadaptation. To test this, we performed an additional experiment (163 broods) in which clutches were either fully crossed, non‐crossed, or partially crossed. In agreement with the long‐term data, there was no evidence for parent–offspring coadaptation on offspring fitness despite high power. In addition there was no evidence of effects on parental fitness, nor evidence of sibling coadaptation, although the power of these tests was more modest.
