None of the above

Explanation:
Detailed explanation-1: -Polygenic Trait A polygenic trait is a characteristic, such as height or skin color, that is influenced by two or more genes. Because multiple genes are involved, polygenic traits do not follow the patterns of Mendelian inheritance.
Detailed explanation-2: -Most commonly, traits are influenced by multiple genes and the environment. So for most traits, patterns of inheritance are complex and unpredictable.
Detailed explanation-3: -Pleiotropy (from Greek pleion, ‘more’, and tropos, ‘way’) occurs when one gene influences two or more seemingly unrelated phenotypic traits. Such a gene that exhibits multiple phenotypic expression is called a pleiotropic gene.
