At the moment, it is only possible to add or amend the information about your grandparents, during the activation process, or after you have received your results.
If you have not been able to get all the information added, or you want to make some changes, you will now need to wait until your results have been issued.
When your testing is completed, log in HERE and view your test. You will see the word 'Research' in the lefthand dashboard, where you can opt in or out.
Opting in by choosing 'Yes, I would like to be part of research..." will show the fields where you can enter grandparentage information.
The information you provide about your grandparentage is used only to validate the sample if it will be used for research purposes. It will not affect or be used in your testing or production of your results in any way.
