So according to the question, you know that using ancestry testing, sibling eight and nine realized they were half sibling of individual three.
00:16
So they share one of the parents.
00:19
And then you can see a one, two, six, seven are all deceased.
00:22
So we have no idea.
00:24
And then individual eight and nine differ in age by six years.
00:33
Individual 11 was confirmed to be the daughter of nine.
00:38
Also, 11 was found to share 25 % of virginia with individual three.
00:43
So no, no ivf, no twin.
00:46
And one to six, seven did not remarry.
00:50
And the question says, based on the data, who is individual 13 not related to? so as you can see that obviously 13 is related to 11 and 12 because they're siblings.
01:03
So these are not the options and 13 is related to uh 9 and 10.
01:12
And also uh 8 is also related to 13 because 8 is 9's brother so basically 8 is 13's uncle so this is they're all related and 6 and 7 seven are also related.
01:27
Now we also know that three and eight and nine, they share one parent, and three and 11 also share 25 % of the dna.
01:45
So three is also related because three and 11, they are related...
