| Object | c1 | c2 | c3 | c4 | c5 |
| A | 1 | 1 | 0 | 0 | 0 |

Given the feature matrix above, and assuming that states can transition in the direction 0 --> 1 only, we can say that:
- It doesn't admit a perfect phylogeny, because characters c1 and c2 are not compatible.
- It doesn't admit a perfect phylogeny, because characters c2 and c3 are not compatible.
- It doesn't admit a perfect phylogeny, because characters c4 and c5 are not compatible.
- It admits a perfect phylogeny
- None of the above

ReplyDeleteI have a doubt! According to the answer sheet, the correct answers would be 'B'. However, if we make the complement of one of the columns (2 and 3), they become compatible among themselves. But, in the case of the columns 3 and 5 this is not possible, even if we complement one of them. Please correct me if I'm wrong about that.
