I need answer to a DNA question..... My spouse has a son whom I am sponsoring with his father. He did DNA twice ,first one in 2010 was 96% and now in 2017 95.22 %. The child is his,the mother is deceased and the standard with IRCC is 99.8%. In this case what can we do.... The child has lived with my spouse all these years and if the child is left behind no one will take care. Please help...
