Thank you

This answer makes sense in light of the randomly distributed shares from each mother, but I am not sure that it would be detectably less than with non-sibling mothers, on a 1-to-1 for cM shares, esp if the mothers were twins.
I know that in my own family we have has serial sibling marriages, but no (known) test subjects alive to test the theory.
Thanks for responding.
