Small population size definition biology
WebA founder effect occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have: reduced genetic … Small populations can behave differently from larger populations. They are often the result of population bottlenecks from larger populations, leading to loss of heterozygosity and reduced genetic diversity and loss or fixation of alleles and shifts in allele frequencies. A small population is then more susceptible to demographic and genetic stochastic events, which can impact the long-term survival of the population. Therefore, small populations are often considered at risk of enda…

In contrast, if the population were made up of 1000 individuals, one accidental death would reduce the population size by only 0.1%.
