When are scientific claims accepted? and when are they questioned and/or rejected?

The answer is;  When the scientific claims are accepted when they are corroborated by scientific data. Experiments are set to collect data and make observations regarding the claims. Based on the outcome, the claims (which will be formulated as a hypothesis) will be accepted or rejected. When the experiment is replicated by different independent scientists and producing predictable results, then the claims become a scientific fact.

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.
