Which of these sentences is true with respect to species? a)two organisms belong to the same species even if they are separated by a geographical barrier, as long as they can mate and produce sterile offspring. b)two organisms belong to the same species even if they are separated by a geographical barrier, as long as they can mate and produce fertile offspring. c)two organisms belong to different species if they are separated by a geographical barrier, even if they can reproduce and produce fertile offspring.

answer; the above statement is (true);

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.
