A. 1. Embryological development is very similar for many animals so it would differ a lot from the DNA.
2. embryological evidence is a poor substitute for DNA evidence because of it's almost universal progression. It would be more difficult to see difference in embryos vs via DNA
D. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. Like the arthralgus of a whale that looks very similar to a terrestrial mammals tells us that the whale evolved from land mammals
C. Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.

B One allele from each parent
Explanation:
You have dominant genes (brown eyes) and recessive genes (green eyes)
In order for a child to be born with brown eyes only one parent needs to have brown eyes. Having green eyes is recessive so either both parents need to have green eyes or neither of them needs to have them. But if one parent has green eyes and the other has brown eyes, then the brown eyed gene will almost always dominate the green eyed one.
