survival of individuals in population because they have alleles
that improve their chances of survival + reproduction

Question 2

Evolution

Answer 2

change in allele freq of certain alleles in gene pool over time due to
natural selection

Question 3

Genetic drift

Answer 3

process of change in genetic composition due to random events
rather than natural selection

Question 4

Migration

Answer 4

movement of population groups due to change in favourable conditions.
Increase gene flow thus there is increase in genetic diversity.
