Admixture mapping of quantitative traits in Populus hybrid zones: power and limitations

Lindtke, Dorothea ; González-Martínez, S. C. ; Macaya-Sanz, David ; Lexer, Christian

In: Heredity, 2013, p. -

Uncovering the genetic architecture of species differences is of central importance for understanding the origin and maintenance of biological diversity. Admixture mapping can be used to identify the number and effect sizes of genes that contribute to the divergence of ecologically important traits, even in taxa that are not amenable to laboratory crosses because of their long generation time or...

Effects of inbreeding on aversive learning in Drosophila

Nepoux, V. ; Haag, Christoph R. ; Kawecki, Tadeusz J.

In: Journal of Evolutionary Biology, 2010, p. -

Inbreeding adversely affects life history traits as well as various other fitness-related traits, but its effect on cognitive traits remains largely unexplored, despite their importance to fitness of many animals under natural conditions. We studied the effects of inbreeding on aversive learning (avoidance of an odour previously associated with mechanical shock) in multiple inbred lines of...
