Answer:

Incomplete dominance

Step-by-step explanation:

Incomplete dominance is a type of inheritance pattern in which two alleles of a gene are not dominant over one another but rather form an intermediate phenotype, which is a blending of both parental phenotypes. It is a non-mendelian inheritance i.e. does not conform to Mendel's inheritance principles.

An example of incomplete dominance is that of the alleles of a flower color gene in four o'clock plant. The alleles for white (W) and red (R) are incompletely dominant over one another, hence, they form an intermediate PINK phenotype (RW).
