Twins effects on eachother?
357346
I'm a twin, and we do have similar traits, we think on the same wavelength, but our personalities differ, i am outgoing, my brother is more laid back. So, i think it's in the genes.i'm like my dad, he's like my mum.

actually, that's not 100% true.  identical twins have the same genotype at birth, so most simple paternity tests would NOT be able to tell a difference.\n\nHowever, as twins age (and we hope they have if you're sleeping with them), certain genes are activated in one and not in the other.  This means that more sophisticated genetic testing MIGHT be able to tell a difference.\n\nOtherwise, we figure you're pretty safe.  I hope it was a good threesome!

With identical twins - the other twin will always be female, as they are a clone of the original female.\nWith the fraternal twin - the other will be either female or male 50/50.

Well there are so many technicalities revolving around this question. While biologically speaking you could call the children sibblings is erelevant to the question. Manly because they will have there own genetic codes.  That is where this becomes quite complicated because genetics deals with more than just genes it deals with traits, DNA, Chromosomes, Blood Types, etc...  As far as them being related, coming from not only the same father, but an identical twin they are going to have very similar genes.  In fact when it comes to there family traits it will be identical.  However no individual, no matter if they are identical will ever have the exact same genetics (in the broad since) as another because that would go against the natural law of diversity.  So sumary exact same family traits, but overall two different people (genetics).

Yes! I have an adopted daughter and I have twin girls. I love all the same but there is a difference in the closeness I think because I gave birth to the twins

I assume you're talking identical twins.\n\nThey'll look as alike as the children of any normal couple. \n\nSince the mothers and fathers are genetically identical, it makes no difference (genetically speaking!) whether\n- one of the twin males marries one of the twin females\n- twin males both marry twin females\n- one of the male twins produces children with both female twins\n- one of the female twins produces children with both male twins.\n\nIn all of the above cases, all of the children will (genetically) have the same mother and the same father!\n\n\nGenetic relatedness can be expressed as a number, from\n1 = genetically identical (i.e. twins), to\n0 = not related at all.\n\nFor any particular gene (which we can think of as controlling one particular physical attribute), this is the probability that the two individuals have the same "version" or allele of that gene.\n\nThe higher the number, the more alike two people are LIKELY to be, although the way genes interact is complex and barely understood. So even though brothers and sisters have an average relatedness of 0.5, you may get some that look so similar they could almost be twins, while some look completely different to one another.\n\nFor two sets of identical twins marrying, average relatedness of their children is 0.5 (same as brother and sister)\n\nFor one set of identical twins marrying one set of non-identical twins, relatedness of their children is slightly less at 0.375\n\nFor one set of non-identical twins marrying another set of non-identical twins, relatedness of their children is 0.25 (same level of relatedness as half-brothers or half-sisters, and double the normal relatedness of first cousins which is 0.125)\n\nInteresting thought that if you and your brother or sister marry two children from another family (as happens from time to time), your respective children will effectively be half-brothers and half-sisters to one another!

No, fraternal twins have DNA that is as similar as brother and sister would be.  That's essential what they are, brother and sister (or sisters, or brothers), but simply born at the same time, since it is two separate eggs being fertilized by two separate sperm.

It is called Chimira(sp) one twin is absorbed into another and usually it is the semen or egg that has the different DNA.  the Saliva and blood are the actual person's DNA and the other is like a brother or sisters DNA

LOL! That is sooooo funny! I started to think that there was something in the water when I went out and saw them everywhere!!\n  "Oh, you have twins too?"  "Oh, how cute, I'm a twin too!"\n "My sister has twins."  "My Grandma is a twin!"  "Our neighbor has twins."   "My dog is a twin!"  Oh that was a little much!\n LOL!

I have known different sets of twins! and there are Unique!!  but by far the most interesting is a Mirror twin!!!  Every thing is oppisit!  one is left handed the other is right ,  one crosses there legs one way the other crosses the other way..  YOU get the point!!

No; there are random / environmental factors at work, as well as heritable factors.\n\nThe % of loops and whorls in prints of fingers / toes is similiar in identical twins, but not identical in placement, nor in other fine detail.\n\nHey! look at your own left and right sides!  The exact placement of veins visible through skin eg at wrist and elbow, or exact fingerprints, is not the same when you compare your 2 sides!  They have identical DNA .... but those random factors affected them differently.

Ahhh...nature versus nurture!  Even the experts cannot say with certainty whether nature and your genetic makeup or your nurturing is what makes up the person. There have been studies done with twins who were raised apart, and found that the twins had MANY things that they did just alike, from little things such as which hand they used to open a letter to bigger things such as they body-type and coloring of the people they fell in love with!  There have also been many studies done as to how poverty, violence, drug/alcohol abuse, sexual/physical abuse and parental abandonment affects children, especially in the birth to age 4 range, and how this shows up in their later life as violence in men and self-abuse in women. So having said all this, I personally feel that it is a combination of both, and sometimes it is neither. There are always the stories of the family who did everything right and still wound up with a drug addicted child or a murderer or rapist on their hands. But if you take a 'normal' family and have them raise a child (by normal I mean average, honest, working, functioning people)you will by and large see differences in that child as compared to a child raised by a disfunctional, abusive, out of control, self-serving family.   Did this answer your question at all?

I'm not sure what exactly you mean? But if you are wanting to know similarities and that it depends on if they are identical or not. Some twins can have everything in common and look a like and some have nothing in common and don't look a like and just because they are identical doesn't mean that they will act alike as well. Twins are born at the same time yes but they are there own person if you get what I'm saying. My mom is a identical twin her and her sister hate each other and have nothing in common except they both lie. Twins also run every generation her her side of the family.

there is when twins are born

Identical twins develop when a single fertilized egg splits in two, leading to two embryos. Because they both came from the combination of the same egg and sperm, they have identical DNA, barring the generally undetectable micromutations that begin as soon as cells start dividing. To a standard DNA analysis, they would be indistinguishable. Yet the parents of twins can usually tell them apart by subtle visual cues, and, while their fingerprints are generally similar, they are not identical.
