Question 33
H

Aphids are small insects. In summer, female aphids reproduce asexually. In autumn, when conditions get colder, aphids reproduce sexually.

Which statement suggests why aphids reproduce in these two ways?

[1]
A

Asexual reproduction gives variation in summer, and sexual reproduction gives many offspring quickly in autumn.

B

Both methods give genetically identical offspring, so the aphids stay well suited to their habitat all year.

C

Asexual reproduction rapidly increases numbers in summer, and sexual reproduction gives variation for winter.

D

Asexual reproduction needs a mate in summer, and sexual reproduction needs only one parent in autumn.
