Which of the following statements about human reproduction is true?

a) mitosis in males is also known as spermatogenesis.
b) sperm and ova are zygotes.
c) oogenesis takes place in the ovaries of females.

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.

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
