What is Life?

Consider the following: A form of life has been created that gives birth to two types of offspring.  
In an acidic environment, the offspring has no reproductive ability (called a son) and in a basic
environment the offspring is a clone of the mother (referred to as a mother).  Are both the mothers
and the sons a form of life in spite of the fact that the sons cannot reproduce?

Both are life
Mothers only
Sons only
