Recent studies have shown that brain development in response to prenatal stress may change by epigenetic inheritance for several generations, independent of genetic predisposition. What You Need to Know About Batten Disease, hyperpigmentation (increased skin darkness) or, genitals that have both male and female parts (intersex), or that look sexually unclear (this sometimes results in infertility), two or more sets of DNA present in the bodys red blood cells, possible autoimmune issues, such as those related to the skin and nervous system, Human and animal chimeras can have two different blood types at the same time. Too many maternal cells for to fight infectious diseases that pass to the fetus cannot return to the mothers body.
