Answer:
polygenic; multifactorial
Explanation:
A polygenic trait can be defined as any phenotypic feature of an organism that is controlled by the action of several polymorphic genes which interact with the environment to produce a given phenotype (i.e., they are multifactorial traits). The polygenic traits are controlled by many genes localized in different regions of the genome (i.e., <em>loci</em>) and exhibit a continuous range of variation, where each genomic region associated with the variation of the trait is called Quantitative Trait Locus (QTL). Some examples of polygenic/quantitative traits include, among others, height, hair color, weight, blood pressure, etc.
Q+ZT -> Z+QT
hoping that's correct or are there any answer choices?
