Sex determination ,when the two sexes participating in sexual reproduction must be somewhat different from each other for a number of reasons.How is the sex of a newborn individual determined? Different species use very different strategies for this.Some rely entirely on environmental cues.Thus,in some animals,the temperature at which fertilised eggs are kept determines whether the animals developing in the eggs will be male or female.

In what condition is crocodile sex formed?
The sex of developing crocodilians is determined by the incubation temperature of the eggs. This means crocodilians do not have genetic sex determination, but instead have a form of environmental sex determination which is based upon the temperature embryos are subjected to early in their development. Crocodile embryos do not have sex chromosomes, and unlike humans sex is not determined genetically. Sex is determined by temperature, with males produced at around 31.6 °C, and females produced at slightly lower and higher temperatures. The average incubation period is around 80 days, and also is dependent upon temperature.
