Male DNA from former sexual partners is often transmitted via transference to a woman who bears children by that male, ending up not only in her immature eggs through her bloodstream in sharing fetal blood, but in her brain, as well, as this scientific study indicates, affecting her chances of acquiring Alzheimer’s disease.
Interestingly, it’s not just semen which carries DNA, or can transfer it. People who receive blood transfusions while in a state of trauma, as is often the case, have been found to sometimes absorb the DNA of their blood donors. Not only can these genes be passed on to offspring once absorbed, they also can and do show up in later DNA tests, skewing results.
Previously, we discussed how male sperm can change the DNA of an immature egg in a female without fertilizing them.
Dr Angela Crean, who led the study, said: “Our discovery complicates…
