Which Mendelian idea is depicted by a cross in which the $F_1$ generation resembles both the parents?

Which Mendelian idea is depicted by a cross in which the $F_1$ generation resembles both the parents?
  1. Incomplete dominance
  2. Law of dominance
  3. Inheritance of one gene
  4. Codominance

Solution

In codominance, both alleles of a pair express themselves fully in $F_1$ hybrid, so, it resembles bath the parents. In incomplete dominance, the two genes of allelomorphic pair are not related as dominant or recessive, but each of them express itself partially. Law of dominance states that when a cross is made between two hamazygous individuals considering contrasting trait of simple character then the trait that appear in $F_1$ hybrids is called dominant. Inheritance of one gene is based an crossing between single traits.
