What is a disadvantage of sexual reproduction?
Less genetic variation in offspring
Offspring are exact copies of parents
Few offspring are produced
Less variety of traits in the offspring
What is an advantage of asexual reproduction?
allows for more genetic variation in the species
few offspring are produced, keeping the population low
offspring are clones, so humans can use this process to produce organisms with the same characteristics
offspring are exact copies of the parent so the species will be able to survive environmental change
