Uh, is there anything special for unrooted trees? Cuz ans key is A and D respectively. I get why it’s D, but can someone elaborate why it’s A though? I thought we still can have clades even If our tree is still unrooted…

Hi!
18 answer - A, because on trees without roots, we can form as many clades as we can, simply by combining all the other individual taxa from one, and so on. Therefore, here we have a much larger number of clades than 4. For example, alpha, a, b, and c can separately form 4 clades, but they can also form 2 clades (Alpha and ABC)

Ty for your response, I thought the same, but on other hand isn’t sequencing data reliable enough for assuming that there are 4 caldes (not the best MTF for sure, B sounded a way better at first). Anyways, I am glad that you helped
