Figure 1.
Effect of parental strain on frequency of white forelock inSox10Dom mice. The frequency of white forelock inSox10Dom /+ mice on either the B6, B6C3HF1, or C3H backgrounds is shown. The total number of animals assessed for head spotting in a particular strain background is indicated above each bar on the plot. The increase in head spotting through successive generations of breeding onto the C3H background suggests a recessive C3H modifier.
