It is possible for twins to have different fathers in a phenomenon called heteropaternal superfecundation, which occurs when two of a woman’s eggs are fertilized by sperm from two different men. Ordinarily, a woman becomes pregnant because one of her eggs has been fertilized by sperm.
Can a person have two different biological fathers?
How is it possible? The biological phenomenon of giving birth to twins with two different biological fathers is called heteropaternal superfecundation. This happens when a second ova released during the menstrual cycle is fertilised by sperm cells of a different man from separate sexual intercourse.
Can 2 men’s sperm fertilize the same egg?
Occasionally, two sperm are known to fertilize a single egg; this ‘double fertilization’ is thought to happen in about 1% of human conceptions. An embryo created this way doesn’t usually survive, but a few cases are known to have made it — these children are chimaeras of cells with X and Y chromosomes.
Can kids have two dads?
Some kids live with two moms or two dads. Why? Because some people have romantic feelings for someone who is the same sex or gender. (Your sex or gender means whether you are a boy or a girl.)
What happens when you mix two sperms together?
Combining two sperm wouldn’t work. There just isn’t enough in a sperm to sustain an embryo early on. What about removing the DNA from an egg, and adding two sperm to that? Theoretically you’d end up with a child with the DNA of both dads, and just a bit of the donor’s DNA.
How can 2 males have a baby?
A gay couple may have a co-parenting arrangement with a lesbian couple. Or a gay man can donate sperm to a single woman or same-sex female couple to have a baby. These days, more same-sex male couples are creating their own families through surrogacy.
What if 2 different sperm enters an egg?
If one egg is fertilised by two sperm, it results in three sets of chromosomes, rather than the standard two – one from the mother and two from the father. And, according to researchers, three sets of chromosomes are “typically incompatible with life and embryos do not usually survive”.

Legal Consequences In most states, children can have only two legal parents, and this leaves some families in limbo. “The reality is many children are being raise by more than two adults, and the courts do not have a remedy,” says Joyce Kauffman, a family lawyer in Boston who has worked on several of these cases.

Can a child have 3 biological parents?
Mitochondrial diseases can be passed from mothers to their children in DNA. Last fall, the New York-based reproductive endocrinologist John Zhang made headlines when he reported the birth of a “three-parent” baby — a healthy boy carrying the blended DNA of the birth mother, her husband and an unrelated female donor.
Can 2 girls have a baby?
Two cisgender women (meaning assigned female at birth) in a relationship cannot become pregnant without some form of assisted reproductive technology (ART). The reasoning goes back to basic biology and how an embryo is formed. To create an embryo, a sperm cell and egg cell must meet in some way.
Can a woman get pregnant while pregnant?
In extremely rare cases, a woman can get pregnant while already pregnant. Normally, a pregnant woman’s ovaries temporarily stop releasing eggs. But in a rare phenomenon called superfetation, another egg is released, gets fertilized with sperm, and attaches to the wall of the uterus, resulting in two babies.

Who is the girl from two dads?
You can’t make a baby with two moms by simply fusing two eggs or adding one egg’s DNA to another’s. Even though the resulting embryo would have the usual 46 chromosomes, this wouldn’t work. The reason isn’t some special string of A’s, G’s, T’s or C’s found in dad’s DNA.
