An oocyte is a female gamete produced during the process of gametogenesis. The every month ovary produces an ovum or egg called as oocyte. . The relative size of dormant oocyte varies from 22 mm to 24 mm. The diameter of growing follicle is 200 μm. The size of graafian follicle varies from 400μm to less than 2 cm during the time of ovulation.
Dormant oocyte 1X, growing oocyte 5X, mature oocyte 25X. Tb primary oocyte is approximately 25 micrometers in diameter. After growth, the growing oocyte will reach 200 micrometers in diameter, and eventually, the mature oocyte could reach 2 centimeters in diameter, in humans.
The answer is either A, the bottleneck effect or C, natural selection. The answer is most likely A because it is hinted that the predator fish was placed in the isolated stream. The predators eating the darters less than 5cm is natural selection though.
