They have different genes.
B. they both contribute to genetic diversity within a population
There was no net change in the given population. The size of the given population remains unchanged.
The explanation behind this is that if we consider the given values-
Emigration- 3
Immigration- 17
Natality- 12
Mortality-26
Therefore,
The overall effect on the population will be=
(Emigration+ Mortality) - (Immigration + Natality)
= (3+26) - (17 + 12)
=29-29
=0
Here the emigration means the number of people who have migrated from the population. Mortality refers to the number of deaths in a given population. Immigration is the migration of people into the population and natality is the overall number of births that have taken place in a population. Therefore there is no net gain or loss in the given population. This exerts no effect on the population keeping it unchanged.
