Which type of genetic inheritance shows a mix of traits rather than both phenotypes being fully expressed?

Incomplete dominance is a type of genetic inheritance where the phenotype of the offspring is a blend or intermediate expression of the traits from both parents. In this scenario, neither allele is completely dominant over the other, leading to a third phenotype that exhibits a mixture of the dominant and recessive traits.

For example, when a red flower (RR) is crossed with a white flower (WW), the result may be pink flowers (RW) in offspring rather than either red or white being fully expressed. This blending illustrates how incomplete dominance works by creating a new trait that is distinctly different from both parent traits.

In contrast, complete dominance occurs when one allele completely masks the effect of another, resulting in the dominant phenotype being expressed exclusively. Codominance involves both alleles being fully expressed in the phenotype, such as in the case of AB blood type, where both A and B antigens are present. X-linked inheritance refers to traits associated with genes located on the X chromosome, which can have different patterns of expression but does not specifically involve blending traits like in incomplete dominance.
