Question 37
H

Seed banks store seeds of rare plant species so the species can be grown again in the future.

Seed banks collect seeds from many different plants of the same species, not from just one plant.

Which statement explains why?

[1]
A

This keeps a wide range of alleles, so the species can cope with future changes or diseases.

B

This makes sure that at least one of the seeds will germinate when it is planted in the future.

C

This stores enough seeds so the species can be planted over a very large area straight away.

D

This keeps only the best alleles, so all of the plants grown in the future will be identical.
