Why is it important for dna replication to be error free

because if it is not then you could have problems.

Explanation:

the dna is like an instruction manual. It tell your cells what to do, and if something doesn't transfer over, the cell won't know what to do.

Ex: if you try to build a car and you skip a step it wont run right.

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.

the answer would be..
