Raccoons can exhibit three types of washing behaviors controlled by a gene that shows incomplete dominance. Some raccoons wash all of their food (WW) and some wash none of their food (NN). The heterozygotes wash some of their food. Two heterozygous raccoons mate. What percentage of their offspring are expected to wash some of their food?
