Patriline-level variability in olfactory learning in the honey bee

Free Access

Table I

Proportion of variance in olfactory learning performances explained by different levels of analysis and corresponding heritability estimates for both the conditioning score (acquisition performance) and the extinction score (resistance to extinction).

		% variance explained	broad sense h²
	between colonies (n = 2)^*	0.4
Conditioning	between patrilines within colonies	11.2	0.22
score	between workers within patrilines	88.4
	between colonies (n = 6)^**	8.5

	between colonies (n = 2)^*	1.3
Extinction	between patrilines within colonies	6.5	0.13
score	between workers within patrilines	92.2
	between colonies (n = 6)^**	15.6

Colonies in which patriline-level analysis was conducted.

^**

Larger set including four colonies in which individual learning performances were measured but patrilines were not characterized (and thus patriline-level analysis was not conducted).
