what are the five conditions needed for a population to stay in equilibrium?
1) very large population: no genetic drift 2) no emigration/immigration: no gene flow3) no mutations: no new alleles can be added to the gene pool4) random mating: no sexual selection5) no natural selection: all traits must equally aid in survival
The five conditions needed for a population to stay in equilibrium are:
1. No mutations: Mutations change the genetic makeup of a population. If mutations occur, the population is no longer in equilibrium.
2. No gene flow: Gene flow is the movement of genes in and out of a population. If genes are introduced or removed from a population, the population is no longer in equilibrium.
3. No natural selection: Natural selection is the process by which organisms with traits that are better adapted to their environment survive and reproduce more than others. If natural selection occurs, the population is no longer in equilibrium.
4. A large population: A small population may experience fluctuations due to chance events that can disrupt equilibrium. A large population is more resilient to these fluctuations.
5. Random mating: If organisms choose mates based on traits that are not randomly distributed, the population may become more or less homogeneous over time, and the equilibrium will be disrupted.
