Final answer:
Human height inheritance is most accurately described by pleiotropy, which implies that a single gene can influence multiple phenotypic traits, including height.
Step-by-step explanation:
Human height inheritance is best explained by the concept of polygenic inheritance, which involves multiple genes contributing to the phenotypic expression of a single characteristic. This means that multiple genes each exert a small effect on height, and the cumulative effect of these genes results in the broad range of human heights observed. This concept is closely related to the idea of pleiotropy, where a single gene can affect multiple traits.
While the ABO blood group system is an example of both codominance and multiple alleles, human height does not follow this simple inheritance pattern. If we consider the options given, pleiotropy is the most appropriate answer since it involves a single gene influencing multiple phenotypic traits, which can include height among others.
