Solution:
As Mendel, on crossing homozygous members for contrasting characters, the dominant trait is expressed in the heterozygous or hybrid condition. Incomplete dominance is a deviation of Mendel's law of dominance where the heterozygous individual instead of expressing the dominant trait, expresses a trait which is a mix of the parent traits. Two types of flower colors are produced in Antirrhinum (dog flower) - red and white. When these two flower types are crossed, the hybrid forms a pink flower showing incomplete dominance.
