The level of variety in the population in future can increase, decrease or remain constant. It completely depends on the environmental conditions in which the population is living.
- If there is any natural disaster in the future then a large number of population loss is there and in this condition the level of variety will decrease.
- If there is constant breeding of mutated population without any natural disaster then the level of variety will increase.
- According to Hardy-Weinberg rule the genotypic frequency remains constant if there is no effect of other evolutionary influences.
