Incomplete dominance explained with examples

Incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele. This results in a third phenotype in which the expressed physical trait is a combination of the phenotypes of both alleles.

Problem:

The shape of the roots of radishes may be long, oval or round. Cross between long and oval produced 159 long and 156 oval. Round and oval produced 199 round and 203 oval. Long and round produced 576 oval. Oval and oval produced 121 long, 243 oval and 119 round. How is root shape inherited in radishes? Draw a punnett square to illustrate the Last cross.
