artificial selectionInter- and intrasexual selection are often assumed to push phenotypes in similar directions, but this must not always be the case. The current study used two artificial selection treatments in an attempt to disentangle the effects of inter- and intrasexual selection in the guppy...

Intra-group and extra-group aggression are not necessarily related and can have different underlying motivational states and consequences in mice26,33. Additionally, it is known that nest building material can decrease inter-male aggression29, specifically when transferred during cage change6,28. Our ...
Intrachromosomal rearrangement between morphs To examine if there were genomic rearrangements between chromosomes carrying each colour allele, linkage maps for three subsets of families that each had fathers with one of the three combinations of Black- and Red-determining chromosomes (Black x Black, ...

The observed biased TE insertion in gene-rich regions within an individual genome (VdLs.17) and the “patchy” distribution among different strains point to the mobile elements as major generators ofVerticilliumintra- and inter-specific genomic va...

Estimates of intra- gametophytic self ing rates were obtained with the maximum likelihood, bootstrap-t algorithm and com- puter program of Holsinger (1987), using t= 100 resamplings for each population. Values of Nm were calculated as estimates of inter- populational gene flow by the ...

Similarly, gynogeneticCarassiuscould receive some of the benefits of sexual reproduction, counteracting the accumulation of deleterious mutations, as well as those of asexual reproduction.
