Hybridisation occurs

An allopolyploid formation consists of the two processes of hybridisation and chromosome doubling. Hybridisation makes a different genome combined in the same cell, and genome “shock” and instability occur during this process, whereas chromosome doubling results in doubling and reconstructing the genome dosage.

The chromosome numbers of 10 Veronica L. species belonging to sect. Alsinebe (Griseb.) Lehm. and sect. Beccabunga Griseb. from northern Iran are given. The chromosome numbers for 3 of the 10 studied taxa, i.e. V. siaretensis E. Lehm., V. ceratocarpa C.A.Mey. (2n = 14) and V. hederifolia L. (2n = 36) are presented for the first time. Our results are compared with previous records.
