WHAT IF? Why did the researchers split each female frog’s eggs into twobatches for fertilization by different males? Why didn’t they mate each femalewith a single male frog?
Fertilization:
a) Briefly describe the process of fertilization in humans,
b) identifying key aspects that stop sperms from different species to fertilize human oocytes, and
c) identifying also key aspects that prevent polyspermy.

The juvenile clownfish has both male and female immature reproductive organs. Clownfish are able to produce both testosterone and 17-estradiol.
