Answer:

b. Barring mutation, the two sister chromatids must be identical.

Explanation:

Prior to meiosis, the DNA is replicated so cells enter division with all its chromosomes having two sister chromatids united at the centromere.

DNA replication is semiconservative: the original DNA strands are separated and new strands are synthesized using the original ones as templates. As a result, each sister chromatid is made of one original DNA strand and a newly synthesized DNA strand, and both should be identical to each other.

<span>Coevolution is a process whereby two species, through their interactions with one another, can influence the evolutionary paths of one another. For instance, what may start as a symbiotic relationship between two species may lead those species to specialize in terms of their strengths such that they evolve characteristics that make them more or less reliant on one another as a result, something that would not have occurred otherwise.</span>
