ANSWER: Only 2
A species is defined as a group of similar populations of organisms whose members are capable of interbreeding, and to produce fertile offspring (children). Species are generally composed of a number of distinct populations which freely interbreed even though they appear to be different in appearance. E.g. the populations of all types of dogs look different but all are capable of breeding among themselves and capable of producing fertile offspring. All types of dogs belong to same species Canis lupus. ‘Population’ is defined as a group of freely interbreeding individuals of the same species present in a specific area at a given time.
