mwjc Posted November 26, 2010 Share Posted November 26, 2010 Does the extraembryonic material in prenatal development (including the umbilical cord, yolk sac, etc.) have the DNA of the mother or the embryo? Sorry if this question is badly-phrased or nonsensical; I'm a curious layman. Link to comment Share on other sites More sharing options...
Debruit Posted November 30, 2010 Share Posted November 30, 2010 The umbilical cord develops from and contains remnants of the yolk sac and allantois (and is therefore derived from the same zygote as the fetus). Link to comment Share on other sites More sharing options...
