A protozoan reproduces by binary fission. What will be the number of protozoans in its population after six generations ?

Options

A. 128
B. 24
C. 64
D. 32

Answer

C

Explanation

Binary fission is mode of asexual repoduces two offspring from parent individual . So,
In 1st generation there are 2 protozonas .
In 2nd generation there are `2 xx 2 = 4` protozoants .
In 3rd generation there are `4 xx 2 =8` protozonas .
In 4th generation there are total 16 protozonas .
In 5th generation there are 64 protozonas .
Thus , ther popluation of protozon will be 64 after six generation .
