Answer:
the SRY gene.
Explanation:
The SRY gene was found within the minimum region of Y-specific DNA required for male development. Confirmation of its role was found by the analysis of XY female patients with mutations within this gene. A mouse has been an important working model to study the process of mammalian sex determination.
It is not really possible to give the exact occurrence of an earthquake, but it can be predicted by monitoring faults. Earthquake happens when the pressure on a fault line builds up or accumulate, when it is eventually releases, earthquake will take place. Geologist observes and measure the changes or amount of pressure in these fault lines to know if an earthquake is likely to take place.
