A Species

A species is a basic unit of classification. All members of the same species are capable of breeding to produce fertile offspring.In sexual reproduction any combination of the alleles of the parents can be passed on to the offspring.Definition:A species is a group of organisms that can interbreed to produce fertile offspring.The binomial naming system is used e.g. Homo sapiens for humans. A generic name is followed by the specific name. The genus is Homo and the species is sapiens.If the species name is not known then the genus name is followed by sp. e.g. Homo sp. An abbreviated genus is also sometimes used e.g. H. sapiens
