Step-by-step explanation:
We khow that the genetic mutation affect 2 percent of the population .
Let's try to understand what does this mean :
- in a group of 100 people there is possibility of finding 2 people with this genetic mutation
- in a group of 1000 the possibility raises to 20 people so we can deduce that each time we add a zero we add a zero in 2
so :
- 100⇒2
- 1000⇒20
- 10000⇒200
- 100000⇒2000
and so on
