Is there a test to prove that people are identical twins?
2 As if children are alike, how they test to see if they twins? My teacher told me how they can have differences in their DNA, because it is a different number of copies of things … So how can prove that they are identical? Yes, but how to "compare the DNA?" Fendergrl97, which is a marker? "
First, the number of amnion ( "bag") or the placenta will not tell the zygosity. These may vary depending on when the embryo splitting. Secondly, DNA is not necessarily identical twins, as you he said. There can be no copy number variation (CNV), which means they can have a difference in some of their DNA. How zygosity was tested by comparing Selected Indicators from 2 twins (and sometimes parents). Normally 8 markers were selected, but may be larger by a reference laboratory. If all bookmarks party, we can say with 99% certainty that the twins are MZ. If you are discordant for 2 or more, we can say with 99% certainty that they are dizygotic.
