The blank for an organism is not related to the blank of that organism

the genus of an organism is not related to the species of that organism

Explanation:

The basic unit of the natural system of classification is the species. The species has hereditary distinction, i.e. a unique set of genes that distinguishes it from any other group. A species is a group of organisms that are morphologically similar and can naturally interbreed to produce fertile-viable offspring. However, organisms can belong in the same genus but different species and are therefore not compatible.
