D) polygenes.
E) All of the above

Question

Quizplus · Accepted Answer

The complete phenotype of an organism is dependent on the genotype, which is the genetic makeup of the individual. However, the expression of those genes can be influenced by penetrance, which refers to the proportion of individuals with a specific genotype that actually exhibit the expected phenotype, and expressivity, which refers to the variation in phenotype among individuals with the same genotype. Additionally, some traits may be controlled by polygenes, or multiple genes that contribute to the phenotype, further complicating the relationship between genotype and phenotype. Therefore, all of the factors listed in choices A through D can influence the complete phenotype of an organism.
