If organisms have developed traits that fit their environment, they will have a better chance of living long enough to have babies. What is this process called?
Natural selection
Cloning
Genetic engineering
Selective breeding
If all the individual organisms of a species completely die off, it is referred to as _________________.

Mutation
Sometimes, mistakes crop up in an organism's genetic code as its DNA sequence is replicated. This is referred to as __________________.
Mutation

An adaptation
A variation
Natural selection
Mutation
What is the general term for a genetic difference in a species that could potentially be good for that species or bad for it?
