Question about twins and sibling test

I'm also calling around for sibling test for her and I as well. If anyone has any information about that let me know. I'm skeptical of the mail in tests.

The gene for multiple births is only carried on the female side. My great grandmother had 2 sets of fraternal twins, one year apart. I miscarried a set of fraternal twins.
It doesn't matter if it is a first pregnancy or subsequent pregnancies,the odds stay about the same for having twins. The gene appears to skip generations also.

Ok thank U!!!


Anyone have a good sibling testing info.

I found 23and me and also Ancestry.com testing - it will links with others that have been tested and in their data base

You should be able to run a regular paternity test with a sample of each of your blood at a genetic testing facility.

What would show in the test if you share the same parent is you would have 50% of your genes in common with each other.

A set of marker genes would be checked for this percentage by the lab,

Look up genetic testing laboratories in your area.

You can also make an appointment with a genetic counselor. This is someone who will assist you in getting the testing and interpreting the results.

Thank U,I read most of that info. online and I called one next to us and he said since my 2nd cousin is my cousin and we can't get the father to be tested - we wont find out if we are siblings- because we will already have dna from our mothers that are related.

So,Im going to ask my nuerologist at the VA hospital if I can take a gentic test and if he will test her for any gentic diseases in our family etc.. maybe I can do that and find out?

Not true. My grandmother was an identical twin, she had my father, and my father had (my sisters) who are identical twins.

I edited that post because I made a mess of it. Left out 2 words and it made no sense. Fixed now!

Also wanted to add, that I don't know if there is a test for the birth order of twins. My grandmother who was a twin were the oldest girls. My twin sisters are younger then me, and were the 4th pregnancy.

I think the twin gene is just that, the twin gene. Each pregnancy has the capability of being a twin.

That's excluding fertility drugs, of course.

Im a twin i had twins and i have tw sets of cousins who are twins one set identical the other not, im not my children arent. So bithe run in my family and bith from my mothers side and im a woman. Twins come from the mothers side as its either one egg that splits with one sperm or its two egss with two sperm dads as far as i know canot influence twins even if its in there genes to

Check your Biology book. Males determine what gender, females determine how many.
