Answer:
decrease in genetic variation
Explanation:
- The genetic drift is the amount the four-factor that affects the mutation, the migration, the genetic drift, and the natural selection and causing the gene pools to change over time and changes are associated with the frequency of the existing gene variations and may cause a disappearance in the number of that species.
- This plays a more important role in the evolving species and the together with the mutation and the migration. There are chances that this can increase or decrease over time and occurs in a small population and with the frequent alteration of the genes that have a greater chance of being lost and a possibility of decreasing the genetic diversity of the species.
