Fig. 4From: Cytogenetic and molecular genotyping in the allotetraploid Festuca pratensis × Lolium perenne hybridsThe distribution and the frequency of rearrangements in rDNA-bearing chromosomes (3L, 2F, and 3F) among F2 and F3 generations of F. pratensis × L. perenne hybrid. Green dots on the chromosomes illustrate 35S rDNA loci; pink dots illustrate 5S rDNA; orange blocks illustrate the position and size of rearrangementsBack to article page
