Derived termsFrom Wiktionary under the GNU Free Documentation License. A twin is one of two offspring produced in the same pregnancy. Twins can either be monozygotic (MZ, colloquially "identical"), meaning that they develop from one zygote that splits and forms two embryos, or dizygotic (DZ, colloquially "fraternal") because they develop from two separate eggs that are fertilized by two separate sperm. In contrast, a fetus which develops alone in the womb is called a singleton, and the general term for one offspring of a multiple birth is multiple. StatisticsTwins are estimated to be approximately 1.9% of the world population, with monozygotic twins making up 0.2% of the total - and 8% of all twins. The twin birth rate in the United States is slightly above 32 twin live births per 1,000 live births, while the Yoruba have the highest rate of twinning in the world, at 45 twins per 1,000 live births, possibly because of high consumption of a specific type of yam containing a natural phytoestrogen which may stimulate the ovaries to release an egg from each side. Due to the limited size of the mother's womb, multiple pregnancies are much less likely to carry to full term than single births, with twin pregnancies lasting only 37 weeks (3 weeks less than full term) on average.

I am 11 weeks and have had an ultrasound and heard both heartbeats but am so scared that something is going to happen to one or both of the babies and they wont make it.

The position of the babies will largely determine how the twins are born - vaginally or by cesarean. About 40% of twins are both head down (vertex) at term, another approximately 30% see the first baby (Twin A) vertex and Twin B breech. Both of these positions are acceptable to consider a vaginal birth. Other positions of the babies like two breeches, two transverse or Twin A breech and Twin B vertex are usually delivered via cesarean surgery. This is usually known ahead of time with ultrasound technology. However, even twins can change positions late in the game and even into labor. This is particularly true of Twin B after the birth of Twin A. Vaginal Birth More than half of twins will be born vaginally.

Q. I m wondering how much is it to rent the diamond twin star or the diamond DA 40? When people say a $90 per hour to rent a plane, is that mean an hour of technical flying? I will get my private license hopefully in three months as I m training right now. I live in Salt Lake City, and I m planning to travel to Santa Barbara for a couple of days in June. Also, how much would be the cost like to park the plane in Santa Barbara s airport? Asked by The Revolutionist - Wed Feb 3 04:41:47 2010 - - 1 Answers - 0 Comments A. A Twin Star will normally rent for around $300-500/hr of flight time (depending on where you live). However if you don't even have a PPL you probably won't have a multi engine add on by June. Most of the rentals I have seen for twins require 250 hours with 50 hours in twins to go solo and most require instrument ratings as well. Getting those by June will be a challenge for you. If you are training with a school that has a Twin Star, ask them what the rental rate would be. Finding Twin Stars is not easy as they are still fairly new. (Utah State may or may not "rent" the two they own - I doubt they do.) Planes are rented either wet or dry. If rented wet then fuel is covered, if rented dry you as the renter pay the fuel.
