Artificial selection for increased maternal defense behavior in mice.
Maternal aggression is directed towards intruders by lactating females and is critical for defense of offspring. Within-family selection for increased maternal defense in outbred house mice (Mus domesticus; Hsd:ICR strain) was applied to one selected (S) line, using total duration of attacks in a 3-min test as the selection criterion. One control (C) line was maintained and both lines were prop...
متن کاملArtificial selection for increased wheel-running behavior in house mice.
Replicated within-family selection for increased voluntary wheel running in outbred house mice (Mus domesticus; Hsd:ICR strain) was applied with four high-selected and four control lines (10 families/line). Mice were housed individually with access to activity wheels for a period of 6 days, and selection was based on the mean number of revolutions run on days 5 and 6. Prior to selection, herita...

15 صفحه اولFitness consequences of artificial selection on relative male genital size
Male genitalia often show remarkable differences among related species in size, shape and complexity. Across poeciliid fishes, the elongated fin (gonopodium) that males use to inseminate females ranges from 18 to 53% of body length. Relative genital size therefore varies greatly among species. In contrast, there is often tight within-species allometric scaling, which suggests strong selection a...
