Re: incest taboos

[Jean-Marc Perreault]

Hi Beth,             My understanding of the biological issue of incest is not so much that offsprings will "automatically" be defective. Rather, when two individuals with a familial link reproduce, the odds of genetic defects being passed on increase, especially if a recessive gene that carries such a defect is present in the bloodline. Thus, even if two sibblings reproduced, it is no guarantee for failure. So the Rohstchilds family example is but a case study. Perhaps they started off with a very healthy gene pool to begin with. It is, however, a good example to disseminate the urban legend that inbreeds automatically have genetic defects related to the familial reproduction. Cheers.
