The albino locus and locomotor behavior in the mouse: studies using extended test intervals.

The influence of albinism upon initial activity in novel surroundings was examined using coisogenic and congenic lines of mice. In comparison with those of previous studies, an extended test interval was used, and this modification produced significant main and interaction effects of the c locus upon activity for both lines. The present findings confirm and extend those of previous studies upon the depressant effects of albinism based upon coisogenic lines, and extend the findings to congenic lines as well.
