What are the factors that influence natural selection?

Genetic diversity within a species, the degree of genetic expression, and the ability of most species to reproduce excess offspring all exert an influence on the process of natural selection. Therefore, it is important to identify the processes that generate genetic diversity within a population.

Correspondingly, what are the major causes of natural selection?

Four general conditions necessary for natural selection to occur are: A. More organisms are born than can survive. B. Organisms vary in their characteristics, even within a species. D. Differences in reproduction and survival are due to variation among organisms.

What are the factors that affect natural selection?

Darwin also named some factors that affect the process of natural selection. Among these were overproduction, competition, and variations. Overproduction happens when species reproduce many more offspring than can possibly survive.

What are the three requirements for the process of natural selection?

The Process of Natural Selection
  • Variation. Organisms (within populations) exhibit individual variation in appearance and behavior.
  • Inheritance. Some traits are consistently passed on from parent to offspring.
  • High rate of population growth.
  • Differential survival and reproduction.
