Jednym z istotnych kierunków badań cytogenetycznych roślin są badania na temat asymetrii kariotypu roślin, rozpatrywanej w dwóch wymiarach: wewnątrzchromosomalnej i miedzychromosomalnej. Do oceny asymetrii używa się współczynników: TF%, Ask%, Syi, Rec, CG, A1, A2, CV, DI, A, CVCI, CVCL, AI. W niniejszej pracy analiza różnorodności asymetrii przeprowadzona w rodzaju Pinus oraz rodzinie Liliaceae wykazała znaczące różnice w przebiegu ewolucji obu grup. Rodzaj Pinus pochodzący z ery mezofitycznej cechuje się metacentrycznymi kariotypami, w przeciwieństwie do znacznie młodszej rodziny Liliaceae (późna kreda/wczesny paleogen) odznaczającej się dużym zróżnicowaniem długości, liczb chromosomów oraz asymetrią kariotypów co przestawiają zamieszczone...
