MERISTIC VARIATION Meaning and
Definition
-
Meristic variation refers to the inherent variability in the number of discrete, countable characteristics or units within a population or species. These characteristics are typically quantifiable and can include traits such as the number of fins, legs, vertebrae, or other body parts. Meristic variation is a form of morphological variation that is usually determined by genetic factors.
This type of variation is distinguished from continuous variation, which involves traits that can vary along a continuous scale (e.g., height or weight), whereas meristic traits are discrete and can only be expressed as whole numbers. Meristic variation can be observed across various organisms, including plants, animals, and even humans.
Meristic variation is thought to result from multifactorial influences, including genetic, developmental, and environmental factors. For example, genetic mutations or abnormalities can lead to changes in the number of body parts. Environmental factors such as temperature, nutrition, or other external influences may also contribute to meristic variation, although their precise mechanisms are not yet fully understood.
Meristic variation has important implications in fields such as evolutionary biology, ecology, and population genetics. It provides a means to measure and understand population differences, genetic relationships, and evolutionary processes occurring within a species. By studying meristic variation, researchers can gain insights into the genetic mechanisms underlying the development and evolution of organisms.

Etymology of MERISTIC VARIATION
The word "meristic" comes from the Greek word "meros", meaning "part, portion, or segment". It refers to the division or segmentation of a body or structure into distinct units.
The term "meristic variation" combines "meristic" with "variation", which comes from the Latin word "varius", meaning "diverse" or "varied". Hence, meristic variation signifies the diversity or variation in the number of discrete units or segments in a particular characteristic or trait within a population or species.
