Which of the following best represents the relation between genetic variation and population size?

• The larger the population size the less genetic diversity. This results in lower genetic variation. This benefits the species.
• The larger the population size the more genetic diversity. This results in higher genetic variation. This benefits the species.
• The smaller the population size the less genetic diversity. This results in lower genetic variation. This benefits the species.
• The smaller the population size the more genetic diversity. This results in higher genetic variation. This benefits the species.
