Competition
Since living space and food are limited, organisms must compete for the necessities.
Variation
Differences between individuals in a population.
Adaptations
Any kind of inherited trait that improves an organism's chances of survival.
Natural selection

For example, the ratio for a single trait of allele will remain 3:1 for a whole population of large numbers
