Analyses of lampbrush chromosomes of C. elongatoides and C. taenia. High-resolution mapping of selected markers on lampbrush chromosomes forming bivalents during diplotene phase of meiotic division and corresponded lampbrush chromosomal maps. satCE04 marker (green) indicates centromere position on all presented lampbrush chromosomes of C. elongatoides (EE) and, C. taenia (TT). satCE01 repeat (red) was localized on lampbrush chromosomes no. 24 in C. elongatoides (a,a’) and no. 20 (b,b’) in C. taenia. satCE05 repeat (red) was mapped on lampbrush chromosome no. 11 in both C. elongatoides (c,c’) and C. taenia (d,d’). satCE03 repeat was localized on lampbrush chromosome no. 19 (e,e’) in C. taenia and on 3 lampbrush chromosomes in C. elongatoides: no. 9 (f,f’), no. 10 (g,g’), and no. 13 (h,h’). satCE02 marker located on lampbrush chromosomes no.6 (i,i’) and no. 14 (j,j’) in C. taenia and lampbrush chromosome no. 8 (k,k’) in C. elongatoides. satCE06 marker was mapped on lampbrush chromosome no.18 (l,l’) in C. taenia and lampbrush chromosomes no. 18 (m,m’) and no. 23 (n,n’) in C. elongatoides Bar equals 5 µM.
