Pigs and Humans do not have a very high percentage of shared DNA. Pigs
do happen to have heart structures that greatly resemble Human organs, and they are of about the right size, so they're useful in medicine. The rabbit/cow thing is based on similar facts. Pig
skin and flesh is also very similar to Human, and is frequently used as a substitute in medical research. (And, according to South Pacific cannibals, and disaster survivors who have been reduced to cannibalism, Human flesh tastes like pork. To this day SPAM remains a popular dish among formerly cannibal tribes in the area, at least according to legend. /forums/images/graemlins/smile.gif Could be worse. We could taste like chicken.)
BUT this is a sci-fi show and we don't know the technology used.
But we
do know that this is a science fiction show that actually has some respect for
science. And we know enough about genetics to understand that you either cannot produce offspring or at least cannot produce
fertile offspring, by mating two completely different species that both come from
this planet. A 99.9% match gets you a mule. A 50% match won't even get you a pregnancy. How likely is it that two species produced by completely different evolutionary histories on worlds orbiting two different suns are going to be able to interbreed with only a partial change in genetics? Franklin may not be speaking with scientific precision when he tells John that Delenn's pregnancy might be dangerous. He's simply aware that there are unknowns involved because the doesn't understand the transformation process, or what Minbari traits might still be expressed through the portion of Human DNA that
is identical to Minbari DNA. And since Delenn isn't exactly a molecular biologist or a genetic engineer, I think we can safely dismiss anything she has to say on the subject.
I just don't see how she could have become pregnant by a Human without being essentially Human herself. That doesn't make sense to
me. As the sign at Cal Tech says, "Never apply a
Star Trek solution to a
Babylon 5 problem. /forums/images/graemlins/smile.gif
