The results suggest incomplete dominance, as in the pink × pink cross, where some offspring showed an intermediate phenotype (red). Also, in the pink x white cross, there were offspring of each parental color as well as an intermediate phenotype (pink). Incomplete dominance occurs when neither allele is completely dominant over the other, resulting in an intermediate phenotype in heterozygotes.
