but are also reproductively isolated from their immediate ancestors. The reason for their reproductive isolation is simple: organisms with different numbers of chromosomes usually produce sterile offspring. An example of this
All of the above figures are based on a 30% adhesion factor. IE, the wheels grip the rail with a force equal to 30% of the loco weight. Locomotives of the GP40/SD40 era and their Dash 2 offspring are generally considered to have an adhesion factor of about 25% not 30%. Sand will...
