Gene flow
<span>Natural Selection </span>
<span>Gene flow occurs
during migration where alleles from one population
are introduced to another population hence increasing the population diversity. </span>
Genetic<span> drift occurs when the allelic frequency of a population changes due factors such as calamities and emigration or natural selection.</span>

Answer:
90%
Explanation:
Frequency of bean plants in the garden that have been eaten can be calculated as the total number of bean plants eaten divided by the total number of all bean plants in the garden.
Given that:
Number of bean plants eaten = 45; number of bean plants uneaten = 5
Total number of bean plants in the garden = 45 + 5 = 50
Therefore, frequency of bean plants in the garden that have been eaten = 45/50 = 0.9 = 90%
Frequency of bean plants eaten in the garden by the deer = 90%
