Can A Baby Have Dna From Two Mothers
Can a baby have two dna? While a baby normally inherits a single, complete set of dna from both parents, resulting in one unique genome, there are extremely rare biological phenomena, such as chimerism or mosaicism, where an individual can indeed possess cells with distinct genetic material. A baby typically inherits dna from two parents. However, advancements in reproductive science allow a child to receive genetic contributions from more than two individuals. Unpack the science of genetic inheritance.
Most of the baby's dna comes from their two parents, with a small percentage from a donor. While fetal dna may clear from a mother's system in a few months to a year following delivery, remnants can remain far longer. Urban myths suggest women retain dna from every male partner for seven years, likely sparked by the presence of genital epithelial cells, but much of this remains unfounded. The process allows the children to get most of their dna from their parents, while also avoiding mitochondrial diseases their mother might otherwise have passed on.
