In brackets is indicated the total number of sequences analysed.

Phy – set of sequences classified using a phylogenetic approach

Unc – set of sequences not classified using a phylogenetic approach. These sequences, nevertheless, show amino acid patterns typical of PRD, HOXL and NKL genes. Ne – negatively charged amino acids; P – positively charged amino acids; A -aromatic amino acids; LP – Less-polar amino acids; NP – Non-polar amino acids; LH – less hydrophobic amino acids; VH – very hydrophobic amino acids; S- small amino acids; T – tinny amino acids; Al – Alyphatic amino acids.
