For example if there is any statement like:
Genetic drift occur due to change in gene pool by chance. It could be due to bottle neck effect, founder effect or migration.
I know that most of the time genetic drift occur due to bottle neck effect or founder effect. Migration can also cause it but most of the time it happen due to other factors.
So if in exam a True/False question came as follows:
Genetic drift is caused by migration. True/False
Then what should I do as I know that it could occur due to migration but some other factors are more prevalent.
How could I know what is inside examinar's head?
I don't know if this forum is correct place to ask exam like questions but I found it has 'Exam' tag so I asked it.
