What are the examples of species and strain?

Strains, races, breeds, cultivars, are subdivisions of a species based on characteristics. Example: You breed a lion with a tiger (you make them have sex). A lion is a distinct species, as is a tiger. That forced sex between two different species results in an animal hybrid that is called a “liger. read more

Different strains of the same species can have noticeably different attributes - for example, a difference in metabolic ability, like the ability to break down a specific sugar. These differences between bacterial strains are due to each strain having different genes that code for different attributes. read more

A strain is a genetic variant or subtype of a microorganism (e.g., virus or bacterium or fungus). For example, a "flu strain" is a certain biological form of the influenza or "flu" virus. These flu strains are characterized by their differing isoforms of surface proteins. read more
