篇名: inheritance
作者: 林教授 日期: 2015.07.11  天氣:  心情:
A group from The University of New South Wales[15] has showed telegony to be a true and valid phenomenon for the first time in a species of fly. Their results were presented at the 2013 XIV Congress of the European Society for Evolutionary Biology in Lisbon[16][17] and the recent Australasian Evolution Society’s conference in Geelong.[18] Earlier, a team of scientists from Oxford, Uppsala and UCL had conducted a similar research[19] and obtained a similar result.[20]

Professor Leonard A. Herzenberg of Stanford University in 1979 for the first time proved that fetal DNA can pass into the mother during pregnancies.[21] Fred Hutchinson Cancer Research Center in 2012[22] has shown that it is not uncommon for fetal DNA to get through the blood–brain barrier and into the brain of the mother.[23]Leiden University Medical Center in the same year published a result which indicates fetal DNA from previous pregnancies can enter the bodies of younger siblings.[24] In 2013, scientists around the globe demonstrated in animals, the significant effect of incorporating foreign DNA.[25][26]

Apart from the above-mentioned, one Chinese scientist has proposed possible molecular mechanisms that may account for the reported cases of telegony.[27][28] The proposed mechanisms include the penetration of spermatozoa into the somatic tissues of the female genital tract, the incorporation of the DNA released by spermatozoa into maternal somatic cells, the presence of fetal DNA in maternal blood, incorporation of exogenous DNA into somatic cells, presence of fetal cells and fetal DNA in maternal blood and sperm RNA-mediated non-Mendelian inheritance of epigenetic changes.
