What are some advantages of the life cycle of an impala and salmon

Female salmons lay up to 1000 eggs and if some of them die the others left can easily reproduce more and for impalas, when pregnant they can wait up to an extra month to give birth and this can really help if the weather isn’t good or so things wrong they can wait a bit longer.

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.
