FOUNDER EFFECTS Meaning and
Definition
-
Founder effects refer to the unique genetic makeup and variation that arise when a new population is established by a small number of individuals from a larger population. This phenomenon occurs when a few individuals, known as founders, migrate, disperse, or are isolated from their original population and establish their own population in a new location or habitat.
In such cases, the genetic composition of the founding population is not necessarily representative of the original source population, resulting in a reduced genetic diversity in the new population. This limited genetic variation can have a profound impact on the evolutionary trajectory of the founder population, as it lays the foundation for subsequent generations.
Founder effects can lead to several outcomes. Firstly, the new population may exhibit a different allele frequency distribution compared to the source population. Additionally, genetic disorders or traits that were rare in the source population may become more prevalent in the founder population due to the increased expression of certain genes.
Over time, the founder effect can influence the genetic distinctiveness and adaptation of the new population, ultimately shaping its evolutionary trajectory. The founder effect is particularly significant in small and isolated populations, where genetic drift tends to have a stronger impact. This phenomenon is widely observed in species colonizing new habitats, undergoing rapid speciation, or experiencing genetic bottlenecks due to population fragmentation or dramatic demographic events.
In summary, the founder effect refers to the establishment of a new population by a few individuals, resulting in reduced genetic diversity and unique genetic makeup in subsequent generations.

Etymology of FOUNDER EFFECTS
The term "founder effects" is a compound phrase consisting of two words: "founder" and "effects".
The word "founder" in this context does not refer to the person who establishes an organization but rather comes from the noun form of the verb "founder", meaning to become impaired or collapse. It originated from the Old French word "fondrer", which meant to sink or fall.
The word "effects" comes from the Latin word "effectus", which means "accomplishment" or "execution". It evolved through Old French and Middle English to become the word we use today.
When combined, "founder effects" refers to the effects or consequences that arise from the limited genetic variation present in a population that has descended from a small number of founders. This term is commonly used in genetics and evolutionary biology to describe the genetic consequences of starting a population from a small number of individuals.
