The term for the condition in which hybrid offspring exhibit a phenotype that is midway between dissimilar traits of parent organisms is incomplete dominance.

Here's a breakdown:

* Incomplete dominance is a pattern of inheritance where the heterozygote phenotype is a blend of the two homozygous phenotypes.

* This is different from complete dominance, where one allele completely masks the expression of the other.

A classic example is the flower color of snapdragons. A red snapdragon (RR) crossed with a white snapdragon (WW) will produce offspring with pink flowers (RW).
