Answer:
1 and 6 are correct
Explanation:
1. A and B are probably closely related - true, as reflected by their close gene sequences which usually represents a very close genetic relationship
2. B and C are probably closely related - false, if their gene sequences are very different then they are probably not so closely related
3. A and C are probably closely related - false, we know A and B are close, and B and C are very different, therefore A is probably also very different
4. B is probably an outgroup while A and C are sister taxa - false, A and B are highly similar
5. A is probably an outgroup while B and C are sister taxa - false, B and C are very different genetically
6. C is probably an outgroup while A and B are sister taxa - true, we know A and B share similar gene sequences, whereas C is distinct.
