adaptation replication genetic mutation homologous recombination
I gave my students this multiple choice question: Over several years, a scientist successfully isolates a species of flower for white color. This year, when the new generation of flowers blooms, one yellow flower is found in the population. Which is the best reason for the appearance of a new flower color within the species?

Only one answer is correct among these 4 choices:
- adaptation
- replication
- genetic mutation
- homologous recombination

Could you tell me which one is correct?

genetic mutation
