The tendency to have fraternal eggs is genetic - - the tendency for ID twins is mere chance. I did a quick search, here is an article. From: http://www.findarticles.com/cf_dls/g2699/0003/2699000346/p1/article.jhtml Twins Two children or animals born at the same birth. Identical, or monozygotic, twins are of the same sex and are genetically and physically similar because they both come from one ovum, which, after fertilization, divides in two and develops into two separate individuals. Fraternal, or dizygotic, twins occur when the mother produces two eggs in one monthly cycle and both eggs are fertilized. The conceptions may take place on two separate occasions and could involve different fathers. Fraternal twins, who are no more genetically alike than ordinary siblings, may be of the same or different sex and may bear some similarity of appearance. Twin pregnancies occur on the average in one out of every 80 to 100 births. However, the incidence of twins reflects the number of twin babies born per thousand completed pregnancies, and it is a fact that many more twins are conceived than are born. The causes of identical twinning are not fully understood. Factors affecting the frequency of twin and other multiple births include the mother's race and age, and the number of previous births. The rate of twin births in Japan is 0.7 percent, while the Yoruba of Nigeria have a rate as high as 4 percent. Dizygotic twinning appears to be a sex-linked genetic trait passed on by female relatives in the same family. The chances of having fraternal twins are increased about five times if a woman is a fraternal twin, has fraternal twin siblings or fraternal twin relatives on her side of the family, or has already given birth to fraternal twins (one in twenty chance). While the rate of identical twin births is stable for all ages of childbearing women, the chance of any mother bearing fraternal twins increases from the age of 15 to 39 and then drops after age 40. For women of all ages, the more children they have had previously, the more likely they are to bear twins. Since the 1960s, fertility drugs have also been linked to the chances of producing twins. The majority of research indicates that fathers' genes have little effect on the chances of producing twins. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted April 10, 2002 Report Share Posted April 10, 2002 > If you decide to do it again, I wish you good luck and congrats. If not, let me pass on what my mother told me when I was pregnant for the third time: > > " I truly believe that we were only meant to have two children per mother. After all, we only have two hands to grab kids with. " > > I have four kids. Does that tell you anything about how well I listen to my mother? Yes. And considering your mom said this to you WHILE you were with your third child - - - I daresay you have my mother for your mother LOL.

Guest guest Posted April 10, 2002 Report Share Posted April 10, 2002 Yes, and Yes. Fraternal, (meaning " brotherly " ) twins are no more genetically alike than any other brother or sister. And yes, they run in families, where the mother has anyone in that side of the family with twins (as they are created by the mother releasing two eggs at once). Identical (non-fraternal) twins are when nature stuffs up and one embryo splits into two by mistake. Not believed to be inherited. Twins occur about once in every 80 births naturally, but with reproductive technology getting more common it's getting closer to one in 70. Incidentally, about half of pregnancies are believed to start out as fraternal twin ones... but for most women nature does " its job " of reducing the pregnancy to one child in the first week or so - it's an evolution thing, to give mother and child a better chance of surviving. Now you know. You're special, LOL. Wow you are brave!

Because if they are, you could be > treading on *dangerous* ground thinking that you won't have > another set of twins next time... LOL > > Fraternal, but correct me if I'm wrong - - - identical twins are by chance. Fraternal twins are genetic, yes? Actually - - I am surely treading on dangerous ground because they ARE fraternal. With ID twins, I might have taken the risk some time ago if left to just chance. <not that chance has been all that sweet to me LOL> Grace Quote Link to comment Share on other sites More sharing options...
Guest guest Posted April 10, 2002 Report Share Posted April 10, 2002 Yes, " functioning " describes how they fit into society, but " autistic " describes what they are on the inside. I think it was Salli who said IQ is the biggest indicator of how well they will adapt, and she's right. The better they adapt, the " less autistic " they LOOK, which means they function well by using coping skills, but doesn't change what they are inside. Imagine you had an artificial leg fitted and you were able to walk. While you would still have a disability, you would be better off than an amputee without the artificial leg. You'd be very close to " normal " . It's all to do with the way we attempt to overcome our limitations. in Sydney, Australia Mum to , 6yo AS ADHD, and , 5yo mild hearing loss Re: i got the dx today Salli- thanks for your take on his test results. I've been thinking about everything you said- and telling other people the same thing- but this is the first time someone came to ME and said it. thanks! I have a question- can a kid be High Functioning and Moderatly Autistic? thanks- Quote Link to comment Share on other sites More sharing options...
