Abstract

Assessed the inheritance of off-base-line CERs by analyzing the performance of 3 strains of house mice and their hybrid crosses (n = 14 each) via the diallel technique of genetic analysis. Several ancillary measures of feeding behavior were also analyzed by the diallel procedure. Significant amounts of dominant genetic action and heterosis were found for the CER, latency to approach food, and eating rate. Significant amounts of additive genetic action were found for the base-line recovery measure, CER, and time in contact with food. Significant epistatic gene action prevented a genetic analysis of the operant bar-pressing measure. Results are concluded to be significant for uncovering evolutionarily important behavioral traits.
