Answer:
Option A, [tex]6[/tex]
Explanation:
Given -
Frequency of change of base pair
[tex]= \frac{10^{-9}}{bp}[/tex] per generation
To calculate the number of base pair changes , the following formula can be used -
Number of base pair changes [tex]=[/tex]frequency of base pair change per generation per base pair [tex]*[/tex] total number of base pairs [tex]*[/tex] total number of generations
Substituting the given values in able equation we get -
Number of base pair changes
[tex]= (10^{-9}) * (6*10^9)* (1)\\= 6[/tex]
Hence, option A, [tex]6[/tex] is correct.
