Color Mutation Percentage Charts

Here are a few examples of the more common color mutation crosses and the expected percentages of offspring that will carry or exhibit the various colors. Remember that these are overall averages, and that it is not unusual to find, for example, a heterozygous beige male that produces more of one color than another instead of half beige and half standard as would be expected, just as it is not unusual to find a male that produces more offspring of one sex than the other.
