i was pregnant with a set of twins. one passed on at 13 weeks enutero and the other made it to 29 weeks before coming a bit early. the twin that passed had (i suppose you could say) mumification going on. when i found out the one twin had died, it was because i thought my water had broken so off to the hospitol to find out it was the passed on baby's fluids, and not her sister. (oh and my daughter born at 29 weeks, she will be 7 this year. best of luck, i hope that helped a bit, i know it's not all sciencey,but that is my story of faternal twin demise.
The other twin is unlikely to survive.
Depends on how they were conjoined.
The death of an identical twin in the womb may be caused by developmental or genetic defects in both members of the twin pair, but one twin fares rather better than the other and makes it to birth alive, as a womb twin survivor. The death of a fraternal womb twin in the womb may be caused by developmental anomalies/genetic defects in the womb twin while the womb twin survivor is developing normally and does not share the same genes. After one womb twin dies later in the pregnancy and there is one placenta, or the two placentas have fused, there is a risk of twin embolisation syndrome in the womb twin survivor, which can cause brain damage to the survivor if delivery is delayed. To avoid this risk, the premature birth of the survivor is considered an appropriate solution. In short, there is a slight possibility of damage to the survivor, but the loss of a womb twin is very common, affecting at least 10% of pregnancies, while the birth of a child with defects is relatively rare.
Vanishing twin syndrome was first recognized in 1945. Vanishing twin syndrome is when one of a set of twin/multiple fetuses disappears in the uterus during pregnancy. This is the result of a miscarriage of one twin/multiple. The fetal tissue is absorbed by the other twin/multiple, placenta or the mother. This gives the appearance of a "vanishing twin." http://www.americanpregnancy.org/multiples/vanishingtwin.html
ya she does and one of them dies im not going to spoil it though,
The dead twin will be still-born and will have not effect on the remaining twin. You do need to speak to your OBY/GYN for more detailed advice.
A Clydesdale can have twins, but that is rare, and most of the time the other twin dies, so normally one.
Once your old tamagotchi dies, hold a+b+c until you hear a beep, let go of b+c, but keep holding a until two eggs appear
A is Mona Vanderwaal until she dies. Then, it is Ali because Courtney her twin sister was the one that really died and Ali was still alive.
One of a Twin was created in 2009.
Ali is not really ali. She has a twin sister named Courtney, who was pretending to be her. She (courtney is the one hwo dies, not ali. Ali is still alive but no one knows it.
Usually one, occasionally two although twin pregnancies generally abort before birth or one foal is dead at birth or dies shortly after birth. Often both twins die. Successful twins are rare. Most breeders use techniques to prevent twin pregnancies.
