There are a few contributing factors in biology which may affect Darwinian puzzles. Coefficient of relatedness (r): the percentage of genes shared by two animals. This may be based on common descent. Animals may share 1/4, 1/2, or even in some cases all of their genes with others. Identical twins have a coefficient of relatedness of r=1.
