    Notes: Abstract Ultrasonic calls produced by young mice elicit maternal investigation and retrieval, and their characteristics have been shown to vary with age and genotype. In this study, we completed a full Mendelian cross of two inbred strains BALB/cJ and DBA/2J. The major result was the detection of directional dominance for a high rate of calling. Other characteristics were influenced by additive and maternal effects in the absence of directional dominance. We estimate the number of loci involved in the rate of calling to be about 1—facilitating studies of a gene-to-behavior pathway.

    Notes: Abstract Though social behavior has not been overlooked by behavior geneticists, the number of studies is small when compared to those on individual traits. One reason for the neglect may be the difficulty of making connections between genes and social behaviors, which by definition involve the interaction of two or more organisms. Fuller and Hahn (1976) addressed this issue and described three means of establishing social groups that would facilitate genetic analysis. We survey the literature on agonistic behavior in mice from 1976 through 1994 and describe interesting uses of those three methods. One of those methods (the standard tester design) often employs a “noninteractive” social partner. We present data showing that the standard tester design may be more valuable when using an evocative and interactive standard tester.

    Notes: Abstract Infant house mice, Mus musculus, produce ultrasonic calls that reliably lead to retrieval by adult mice. While individual differences in calls have been demonstrated both among and within species, the influences of age and sex on call characteristics have not been systematically investigated in mice. This study examined the influences of age, sex, and genotype (inbred versus hybrid) on the rate, length, and frequency characteristics of the calls of 486 male and female mice from 2 to 12 days of age. Rate of calling followed a shallow inverted U-shaped function across days. Call lengths decreased and call frequency characteristics increased, in a linear manner, with age. Females emitted fewer calls, with a smaller bandwidth, at some ages than males. Hybrid pups produced more calls of greater length and a lower frequency than inbred pups. These results indicate the presence of cues that could allow adult mice to behave differentially toward pups as a function of their age and sex.

    Notes: Abstract The genetics of social behavior presents special difficulties because the phenotype is the product of an interaction between two or more individuals. Social interactions are of two kinds: (1) cooperative, in which the probabilities of transmission of the genes of all participants are similarly affected by the outcome, and (2) agonistic, in which the probabilities for the participants are affected in opposite directions. The latter are of particular interest for evolutionary theory. Three major types of designs for measuring social behavior in genetic experiments are available: (1) homogeneous sets, (2) standard tester and (3) tester panel representing a reference population. The advantages and limitations of each method are discussed. Important areas for future development include the relationship of genetic and experiential factors in early life to social status as an adult and the extension of the genetic analysis of social behavior to natural populations.

    Notes: Abstract Ultrasonic calls produced by young mice reliably elicit investigation and retrieval by adults. While there are large individual differences in the characteristics of these calls, little work has been done to partition that variation. We completed a 4 × 4 diallel cross and Hayman analyses on several characteristics of these cries. The major result was the detection of directional dominance toward a higher rate of calling, longer calls, and calls of lower overall frequency with a greater bandwidth. Within the context of biometrical genetic theory, we conclude that calls with such characteristics may have important fitness value. Extending this idea, we propose that within the population sampled for this study (the animals of the four inbred strains and 12 F1 hybrid groups), the calls most effectively eliciting investigation and retrieval would be calls with the average hybrid values of the diallel cross.

    Notes: Abstract The inheritance of brain and body weights was analyzed via the diallel cross. Results indicated some conjoint and some separate genetic influences on brain and body weight. The results are discussed with respect to Darwinian fitness.
