Why is 2 the correct answer to number 22 ? explain why and answer this

Meiosis is performed in order to produce four gametes (sex cells). (1) is not correct because the eggs and sperm are NOT exactly the same. (3) is also not correct because I believe meiosis only produces 1 active egg cell and 4 active sperm cells. (4) is not correct. Thus, option (2) is correct because it is both true and valid. Since the cells that are produced are not identical, meiosis provides for genetic variation in the gametes produced by an organism. That reasoning also reasons out option (4).

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
