You have three species a, b, and c. assume that they form a monophyletic group
a's gene sequence is very similar to b
a has some physical similarities to b.

b's gene sequence is very different from c's
b has some physical similarities to c
select any answers that are correct
1. a and b are probably closely related
2. b and c are probably closely related
3. a and c are probably closely related
4. b is probably an outgroup while a and c are sister taxa
5. a is probably an outgroup while b and c are sister taxa
6. c is probably an outgroup while a and b are sister taxa

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.

answer: all : )
