ELI5 What are the differences between clementines, tangerines, and other orange-like fruits?

They are all quite closely related. All modern citrus fruits are a genetic mix of 3 original species: citrons, pomelos, and the true mandarin. Due to this close relationship, any citrus fruit can cross pollinate with any other citrus to create a different variety.
