Hi Gerald,

These salamanders reproduce parthenogenetically. There is a detailed  
description of the process of parthenogenesis in the Wikipedia at:

http://en.wikipedia.org/wiki/Parthenogenesis

I'm no longer 14, but it should not be difficult to understand so  
long as one knows what a chromosome is.

Best wishes,

Chris
