The premise and plot of this episode were very good, but the racial composition of the crew's descendants was so big of a flaw it took away from the rest of the episode. I'm willing to suspend disbelief for DS9 (as well as all the other Star Trek franchises/movies) to allow for the somewhat distinct races that still exist 300+ years into the future. But in this episode, there have been another 200 years (8-9 generations) with the full 8,000 person population all stemming from 40 or so people. There is just no way there would still be "black" & "white" people. (Don't even get me started on the redheads!) This would be one multi-racial group. And how there were still "pure" Trills, with only one to begin with, is a mystery. At the very least, the Trills would also be Klingon descendants. For one episode they could have cast a group of racially ambiguous people. (As noted in the "goofs" section, each descendant would likely have the same amount of DNA from the original crew, so racial distinctions would be minimal if any.)
