If I were to go back in time to the 9th century ad, would it be biologically possible to have a child with my distant grandfather? How genetically dissimilar are we?

weird question, however, wouldn’t be that similar honestly.

If we look at it in basic terms, you are half your mother and half your father. They in turn are half of each of their parents.

so it’s be 1/2, 1/4, 1/8, 1/16 and so on and so forth. the further back you go the less genetically similar it is. However there is some important depended on which genes are carried through that whole tree to if there are issues with the child. Should probably be fine though.
