Conclusions

From the analysis of the loci, we can exclude Child 1 as coming
from those grandparents. Even with the possibility of mutation, the
mutation rate is not high enough to make the number of differences we
see. Child 2 matches for all loci, which supports the claim of ancestry.
Without more probability information, we cannot conclude unambiguously
that the child came from this family.
