3 Consider a coral reef in the Atlantic Ocean: a species of clown fish are known to live all throughout this reef.

Page 30: Unit #7 Exam Review Quiz

29 Which of the following situations describes diversifying natural selection:

A Kudu are common prey for lions, and the fastest kudu in the group are more likely to survive an attack and pass on their genes. Thus, the population as a whole gets slightly faster with each generation.

B A population of gray mice is prey to nocturnal owls. The mice range in color from white to black, with most being gray. These gray mice are most likely to be spotted by the owls & over many generations the mice begin to split into separate species of white mice and black mice.

C Horses and zebra will often mate in the wild and produce a hybrid. These offspring are sterile, thus they can never create their own population.

D A population of hippo range in size from very small to very large. The smallest rarely pass on their genes due to their inferior stature, while the largest rarely make it to adulthood due to their high caloric demands. Thus, over many generations, the hippos within this population begin to resemble the average-sized hippos from the original population.
