The temperature! If it is between 31.7degrees C (89 degrees F) and 33.5 degrees C (94 degrees F) it will be a male, but if the temperature is outside that narrow 2.8 degrees than it will be a female.
The sex of crocodile hatchlings is determined by the average temperature during the middle third of their 3 months incubation period. If the temperature inside the nest is below 31.7 °C (89.1 °F), or above 34.5 °C (94.1 °F), the offspring will be female. Males can only be born if the temperature is within that narrow 5-degree range.
mmmm... they are probalby inside them and when is the moment to do whoopie it comes out from a puch-like thing that they have, the same thing does the roosters to chickens.
You will know a crocodiles gender as soon as you determine what sex they are.
The temperature at which the eggs are incubated influences the sex of the offspring.
the temperature
what determines the sex of a crocodile
humidity
Depends on the age, sex and size of the crocodile.
Apart from determining what sex the crocodile will be, if the temperature is too cold this will cause the nile crocodile to go onto the river banks to soak up the sun's rays. If it is too hot, the nile crocodile will go into the rivers and lakes and in the shade :)
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.

crocodile calling me,,, crocodile calling me,,,
the answer is sex chromosomes
Depends on the age, sex and size of the crocodile.
The temperature they are incubated in.
In humans, which sex chromosome determines if an offspring is a male or female?
sex
the father
Crocodile embryos do not have sex chromosomes (which determine the sex of a child in humans) and sex is not determined genetically in crocodiles. The sex of a crocodile is determined by temperature -- with males around 31.6 degrees Celsius (89 degrees Fahrenheit) and with females at slightly lower or higher temperature.
The male has an x and a y sex chromosome. The female has two x sex chromosomes.
gametes
A Nile crocodile is classed as a reptile because they are cold-blooded, they lay hard-shelled eggs, they have scales and they have sex but don't give birth to live young.
No, the male determines the sex of a child.
