b. Translocation

c. Deletion

d. Duplication

Question 10: Unicellular organisms such as bacteria depend on asexual reproduction. Why is sexual reproduction so common in higher multicellular organisms such as humans?

a. Because a sexual population can grow faster than an asexual population

b. Because it requires less energy

c. Because it produces offspring that are identical to the parents

d. Because it creates genetic variation in the population

d. Because it creates genetic variation in the population
