Two peas in a pod!




Well it's official! My little guys are genetically identical according to the DNA testing that was done in the 'tooth emergence and oral health in twins and their families' study that we are enrolled in.

The results specifically say that the boys share 20 of the 20 Alleles tested in common. The 20 alleles tested cover 10 loci with one allele coming from mum and one from dad. Of the 10 loci tested Max and Blake have all 10 loci exactly the same. The likelihood of Max and Blake sharing all 20 alleles at these loci by chance and being different at other loci (being non-identical) is extremely low - less than 1 in 10,000 Billion in the case of our twins!

So there you go! I can't say I am really surprised as some days even I struggle to tell who is who but in general I can see differences between the boys. If they are side by side I can tell you fairly accurately which one is which.
