A scientist studies the DNA in corresponding genes of a platypus, a

beaver, and a duck. The DNA from which two species are most likely to be most

similar? Explain your answer.

Respuesta :

Answer:

platypus and a duck has similar DNA.

Explanation:

There are certain similarities which are present between duck and platypus such as structure of beak or mouth, webbed feet and laying eggs in order to continue its generation. These three characteristic make the platypus and duck similar to each other. There is also one major difference is present which is that the platypus is the only mammal which lay eggs and feed baby with their own milk. Its tail structure is also different from duck.

The DNA from platypus and beaver are most likely to be most similar because these species share a more recent ancestor.

  • Sequence homo-logy refers to the level of similarity between nucleotide (DNA) sequences due to shared ancestry in the evolutionary history of life.

  • The species that share a more recent ancestor exhibit a higher level of sequence homo-logy than unrelated species.

  • In this case, the linear order of nucleotides in DNA from platypus and beaver are most likely to be most similar because they are mammals, while ducks are birds.

In conclusion, the DNA from platypus and beaver are most likely to be most similar because these species share a more recent ancestor.
