Question 26
H

A collection contains these six species:

*Panthera leo*, *Panthera tigris*, *Panthera pardus*, *Felis catus*, *Felis silvestris* and *Lynx lynx*.

New evidence causes scientists to move *Felis silvestris* into a newly named genus. The other names remain unchanged, and no species are combined or divided.

Consider every possible pair of different species in the collection.

How does the number of pairs sharing a genus change, and how does the number of genera change?
