In a flower garden, the gardener has purple and white pansies. he notices that a new pansy has sprouted. when it finally flowers, the pansy is lavender. explain how this happened.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
