A family has four genera, with , , and species. How many species are there in the family? What fraction of them is in the largest genus?
Need a reminder? The key ideaShow
The ranks from the smallest: species, genus, family, order, class, phylum (division in plants) and kingdom. A group at any rank is a taxon. Going up, a group holds more organisms that share fewer features. A species is a group with fundamental similarities, whose members can breed and have fertile young.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. Species. species.
Step 2. The fraction. .
Answer: species; of them are in the largest genus.
