There will be 3 phenotypes observed if incomplete dominance is occurring in this organism.
<h3>What is incomplete dominance?</h3>
The so-called incomplete dominance is the one in which the alleles are expressed in heterozygosity, however, they produce an intermediate phenotype, since none is totally dominant. In the case of complete dominance, the phenotype is equal between zygotes and heterozygotes.
With these information, we can conclude that there will be 3 phenotypes observed if incomplete dominance is occurring in this organism.
