河狸亲缘信息素的遗传力:遗传关系的信息是怎样编码的?(英文)

Heritability of kinship pheromone in the beaver:how is information about relatedness coded?

本研究利用几种亲缘关系对河狸 (Castorcanadensis)肛腺分泌物中的单个化合物和其整体组合的狭义遗传力进行了估算。使用气相色谱和质谱对河狸肛腺化合物进行定性和定量分析 ,发现了单个化合物的遗传力很低 ,但化合物的整体组合却显示有适度的遗传力。因此 ,我们认为亲缘关系的编码可能涉及多种化合物 。

We attempted to estimate the narrow sense heritability of single compounds and whole profile of the anal gland secretion (AGS) with the regression method using several sets of relatives in the beaver Castor canadensis. We used GC (gas chromatography) and GC MS (mass spectrometry) to characterize and quantify chemical compounds in beaver AGS. We found that the heritability of single compounds seemed to be low, whereas the heritability of AGS profile appeared to be moderate. We conclude that many compounds might be involved in the coding of genetic relatedness, which was through a combination of analog and digital coding using many compounds.
