What's going on?
Well, I have headed back to work while we await this mess to be fixed. In the meantime we have proceeded with the sibling DNA testing and have found out that our file has been assigned to someone in Ottawa to be reviewed. We hope to hear something from them mid June. Hopefully if we can keep the pressure on then we can get some sort of answer sooner rather than later. AS for the DNA....it could take months. We have been told that there could be up to a 6 month wait just to do the test in Addis so hopefully H can pull through for us and get ours expedited.
Here is some information regarding sibling DNA that makes us wonder why they are making us waste our time and money........
Limitations of Sibship Testing
In paternity and maternity testing, there are certain obligatory paternal and maternal genes which must be present in both the child and his/her biological parents. Obligatory genes are genes which must be present in order for a positive relationship to be established. This allows conclusive results for all parentage testing cases. The limitations in sibship testing lie in the fact there are no obligatory sibship genes. Therefore, even if none of the genes examined are shared by two siblings in a sibship analysis, it cannot be concluded that the two people are not true siblings. This is because the inheritance of genes from the parents is a random event. Thus, it is possible that by chance, less than 50% of the genes are common or maybe even none of the genes are shared. Thus, even if two people do not share any of the genes examined, we cannot conclusively state that they are not true siblings. This can be compared to the tossing of a coin. Theoretically, when a coin is tossed the chances of getting heads or tails would be 50/50. However, we do not always observe a 50/50 ratio. If a coin is tossed six times, theoretically, we should observe heads 3 of the six times and tails 3 of the six times. However, it is possible, though unusual, that we would observe only heads or only tails all six times.
