Fraternal (non-identical) do not share the same placenta as they are two babies formed from two eggs and two sperm. If they implant close together they may appear to be one placenta, but they are not. Identical twins formed from one egg and one sperm may split at any stage from the two cell right up to late in embryonic development which produces conjoined (Siamese) twins. The later in embryonic development the split occurs the more likely they are to share a placent.
Identical twins can go the whole way from separate placentae through to sharing organs,as in conjoined twins. It depends at what stage of the pregnancy the embryo splits in two. The earlier it occurs the more separate the placentae, cords etc.
My twin sister and I were born 9/11/41. The Dr. Traywick told my mother that we would be identical, because we were on a Y-shaped cord or connected cord. He had delivered hundreds of babies in that little west Texas town.
But we were not identical, as anyone could see even in baby pictures. She looks like mom's family, and I resemble dad's. We do have many similarities, however.
We are a third kind of twin--half-identical. The egg divides first, into two identical eggs, and each is then fertilized seperately, so we have identical genes from mother, and different genes from our father. Our grandmother and grandfather raised laying hens, and sometimes we would find a double-yolked egg. Well, we two are from a double-yolked egg, so to speak.
Linda and I have always been exactly the same height, and we began our first menstrual period on the same day. (Each of us thought the other was lying.)Our three sisters did not start their periods at the same age we did. We also began menapause the same year though we lived half a continent apart. If one of us has a physical problem, we call to see if the other one has it too!
Our brother and his wife have identical twins, so identical they could fool their mother when they were young. I don't know about their umbilical cords.
My conclusion is that twins can share the same umbilical cord. We did.
Identical twins have to same cord but non-identical do not
The umbilical cord connects the navel of a fetus with the placenta. When the baby is born the umbilical cord is cut. The belly button is the location where the umbilical cord connected to the placenta.
Fraternal twins each have their own umbilical cord, just like they have their own sac. The two of them are just the same as two siblings with the same birth date.
An umbilical cord is made out of the same stuff that a baby is made out of, it contains blood vessels.
The placenta, cord, embryo are all devoloping at the same time.
Same place as humans. Where their belly button goes.
do identical or non identical twins share the same placenta
Calves will show an umbilical cord until it has dried and fell off, it is simply just the length that is left over until it has dried so no infection enters the belly button. This is the same as human babies.
no.I have been researching on twins and it has been proven on other websites like ask.com and yahoo answers.com that twins share the same features but not personalitys and interests!
It's where your umbilical cord was attached to your body that's why some people have innies and outies, because it depends where your doctor cut itWhen you grow inside your mother's stomach, you recieve all your nutrition and oxegn through an 'umbicalThe reason you have belly buttons is because when you are born you have an umbilical cord which is taken off or often falls off.belly buttons are what connect to the umbilical cord from the mother so some of her food gets transformed into energy for he babybelly buttons are what connect to the umbilical cord from the mother so some of her food gets transformed into energy for he baby
yes cuz the mother and baby might have same blood type
twins
If they are related then they are twins?
