Although most ecotypes (including those widely geographically isolated) are morphologically similar, have the same chromosome number (2. = 42), and are easily crossable, some of them are nevertheless reproductively isolated, as evidenced by t

Pairing between chromosomes of two taxa can also help determine phylogenetic relationships. Therefore, any factor(s) that control chromosome pairing have phylogenetic, evolutionary and breeding implications (Jauhar 1975f, 198
