Answer:

When the rule of 70 applies to population, dividing 70 by the percentage of population growth should equal the time (in years) that the population needs to be double (option A)

Explanation:

The rule of 70 is useful to calculate the time in which a variable of any type can be duplicated. The calculation is done by dividing the number 70 by the percentage of growth of the variable.

<u>If the rule of 70 is applied to the population, it is possible to calculate, based on its growth rate, the time that population would need to double</u>.

If, for example, the growth rate of a population is 3 percent:

70 / 3 = 23,33

This indicates that a population, with a growth rate of 3% would need about 23,33 years to double.

A genetic counselor can also use the principles of population genetics in his advising. What is the basis for this type of couns
Montano1993 [528]

It is associated with more or less why a genetic counselor would need to look at distinct human populations, with which an individual is related to when doing certain kinds of tests. For instance, if someone knows about their ancestry then the counselor would be able to tell about the genetic disorders most commonly occurring in that particular ancestry.  

The basic way of seeing at it from a population genetics point of view is how populations do differ genetically and how does it associate with the probabilities of exhibiting a mutation in the person.
