As expected, this ratio is significantly lower ( p-value < < 0.001; Fisher’s exact test) in the deep portion of the tree and the comparison among domestic branches reveals slightly significant differences ( χ 2 p-value = 0.026) (Table 3 ); in particular the ɷ ratio of A is much higher than previously reported (ɷ = 0.049) [ 17 ].
