If it came from Dad it will express as Angelman Syndrome. Hibernia86 Some genes are methylated covered up so that they are inactive. Genes from the father might be less likely to be methylated than those from the mother.

And the research does not make a quantitative assessment but rather a qualitative one of genetic material. Mitochondrial DNA from the mother is really the one that makes up most of everything.
The sperm, although containing some amounts of DNA, is insignificant except for determining the gender. Plus, the sperm is much smaller than the egg, disabling it to contain more DNA than the egg.
Both egg and sperm cells are the result of meiosis and contain a single chain of DNA. When fertilization occurs the two chains zip together and begin controlling the metabolism of the egg. Those mid piece mitochondria get fructose from the seminal fluid, convert it to glucose and then generate ATP.
It either produces working mitochondria or the egg starves. Hibernia86 Very interesting theory. Though it seems like it would be hard to tell in any case who the father was without genetic tests to be sure. Casting no aspersions, as humans can be so compassionate as well.
Tell me, where are the men who are being killed and abused en masse by women?(1)There have been no long-term follow-up of egg donors, with the result that, so many years after the beginning of hormonal stimulation for egg donation, we still do not know if there are any long-term health risks such as various cancers or infertility for the young women who donated eggs.
