Question 8 of 9

1

Select from the dropdown lists to complete the text.

A ( Species, Kingdom, Class, Genera ) is made up different species with important common features while ( species, genus, strain, subgroup ) is made up of collection of strains and belongs to the lowest level of taxa. ( Subgroups, Genotype, Strains, Taxa ) are genetic variability within species. Biovars are biochemical or physiological differences. Morphovars are morphologic differences and Serovars are differences in antigenic properties.
