"Pleiotrophy" Natural Recordings by Native Speakers
Pleiotrophy refers to the phenomenon in biology where a single gene influences multiple seemingly unrelated phenotypic traits. This means that a single gene can have multiple effects on the phenotype of an organism, often in different ways. The term was coined by the British geneticist Charles Sutton in 1942.
The Pleiocene epoch refers to a geologic age within the Cenozoic Era, spanning from approximately 5.3 to 2.6 million years ago. It is divided into two sub-epochs: the early Pleiocene (5.3-4 million years ago) and the late Pleiocene (4-2.6 million years ago). During this time, the Earth's geology and climate underwent significant changes, including the formation of many modern mountain ranges and the expansion of grasslands and savannas.
Pleomorphic refers to the quality of having multiple forms or shapes, often in a way that is variable or unpredictable. In biology, it describes organisms or cells that can take on various forms, such as cancer cells which can transform into different tissue types. In other fields, it can also describe systems, processes, or patterns that exhibit multiple forms or structures.
Pleiospilos: A genus of succulents in the family Aizoaceae, native to southern Africa, characterized by their unique, stemless, leaf-like structure that resemble stones, which helps them to protect themselves from harsh desert conditions.
Pleiotropical refers to something that has multiple effects on different subjects or fields, often in a way that is detrimental or of mixed value. The term "pleiotropy" itself has a broader meaning, referring to a relationship between two distinct traits, behaviors, or characteristics that is not straightforward or simple. The term “pleiotropical” is often used in biology and ecology.
