$F_1$–generation does not resemble either of the parents.

Answer
$F_1$–generation does not resemble either of the parents: In incomplete dominance, a heterozygous organism carrying two alleles wherein one is dominant and the other one is recessive, (e.g., Rr). Hence, the heterozygote (Rr) will have an intermediate phenotype and will not resemble any parent.
Incomplete Dominance:
It is a phenomenon in which the $F_1$ hybrid exhibits characters intermediate of the parental genes. Here, the phenotypic ratio deviates from the Mendel’s monohybrid ratio. It is seen in flower colours of Mirabilis jalapa ($4$ O'clock plant) and Antirrhinum majus (snapdragon), where red colour is due to gene RR, white colour is due to gene rr and pink colour is due to gene Rr.
