Question

why is genetic variation so sought after and important when organisms reproduce?
it is important in cloning the organisms.
it ensures that the organisms will survive, because they wont all die off from the same thing.
it ensures that dna is exactly replicated in the offspring.

Explanation:

Genetic variation provides a range of traits in a population. If all organisms were identical genetically, a single - threat like a disease or environmental change could wipe out the entire population. With variation, some individuals may have traits that allow them to survive such threats. Cloning reduces genetic variation, and genetic variation does not ensure exact DNA replication (which is more about DNA replication mechanisms).

Answer:

It ensures that the organisms will survive, because they won't all die off from the same thing.
