|MadSci Network: Genetics|
One of my professors mentioned something about the first born child leaving behind a small amount of cells that attack and insert their genetic patterns into all fertilized eggs that occur afterwards. Thus, your younger siblings would have more in common with you than your parents? Is this true? What more can you tell me about this? If it is true, what about the case of a woman giving birth to two children from different fathers? Would the second resulting child have genetic materials from the mother, the father, and the previous father via. first born child?
