Genetic analysis of social behavior in squids

在这项研究中，我们调查了椭圆形鱿鱼社会群体中个体行为差异的遗传背景，即“个性”。对圈养群居鱿鱼进行标识，并记录其行为。从组织样本中提取DNA。进行微卫星基因分型和线粒体DNA测序，并与行为学资料进行比较。我们发现，特定的行为特征，如大胆或活跃，是地区群体的特征。在现有结果的基础上，我们将对候选基因进行筛选，作为资源管理和育种技术开发的目标。

In this study, we surveyed genetic background of the individual difference in behavior namely "personality" within a social group of oval squids. Captive group-living squid were identified by marking and their behaviors were recorded. DNA was extracted from tissue samples. Microsatellite genotyping and mitochondrial DNA sequencing were conducted to compare with behavior data. We found that specific behavior traits such as boldness or activity were characteristic in regional groups. Based on the current result we will survey candidate genes which can be the target of selection for resource management and technical development for breeding.
