Chromosome spreads at metaphase in the gynogenetic offspring (G-1, G-2, and G-3) and backcross progenies (H-1, H-2, and H-3) of 4nRB. A: The 100 chromosomes of G-1, in which no largest submetacentric chromosome was found; B: The 148 chromosomes of G-2, in which a pair of the largest submetacentric chromosomes (arrows) were indicated; C: The 150 chromosomes of G-3, in which the largest submetacentric chromosomes from BSB was absent; D: The 100 chromosomes of H-1, in which the largest submetacentric chromosome from BSB was absent; E: The 150 chromosomes of H-2, in which the largest submetacentric chromosome from BSB was absent; F: The 198 chromosomes of H-3, in which a pair of the largest submetacentric chromosomes (arrows) were indicated; Bar in A-D, 3 μm.
