That seems impossible! Jeff, do you really think that result may be ture? If that is really true, the rule of basic genetics will be rewritten. How amazing the result is!
This is a new hypothesis, but it may be work better with the existing theory together.ffice ffice" /> The existing theory is based on the following findings. 1. The gender of the baby is defined by 雌性哺乳动物卵子是接受X精子还是Y精子, which both are given by the father. 2. The fastest and strongest 精子 will win the competition to reach and penetrate the 卵子 first, which make others being refused and dead. 3. Since the winner’s type, X or Y, will define the gender of the baby, the father’s contribution should determine the gender of the baby. If the new hypothesis can be hold on by the further researches, the new theory will become like the following outlines. · The gender of the baby is defined by 雌性哺乳动物卵子是接受X精子还是Y精子, which both are given by the father. · The fastest 精子 will win the competition to reach the 卵子 first. · The 卵子 has acceptant ability biased to X精子 or Y精子, depending on 卵子内的睾丸酮水平. · So that there will be another 精子competition for penetrating the 卵子. The fastest 精子 has timely advantage in the competition but still may or may not win the battle. · The winner will be finally determined by the combination advantage of the both contributions from the father and the mother. |
