What is the key to the recognition of incomplete dominance?

1. The heterozygote expresses the phenotype of both homozygotes.





2. The trait exhibits a continuous distribution.





3. The dominant allele is not always expressed.





4. The phenotype of the heterozygote falls between the phenotypes of the homozygotes.





5. The alleles affect more than one trait.

Reply:Lobster is right!


People having blue eyed and green eyed parents have blue-green (cyan) eyes for instance.
Reply:questions seem oddly worded but 1 and A seem correct. Incomplete dominance is definitely showing traits from both alleles and this is different from codominance where the two alleles affect phentotype is seperate, distinguishable ways.
