FIGURE 9. Ideograms for N. papyraceus (El Lancón population), N. gaditanus (El Rompido population) and N. ×weickertii (El Lancón population). A, ideograms constructed with the absolute length of chromosomes; mean values (in µm) and standard deviations are represented for the length of each chromosome arm. B, ideograms constructed from the normalized values for lengths of chromosomes; chromosomes of N. papyraceus (genome P, in dark grey shaded) are interspersed with those of N. ×weickertii (light grey shaded) putative of the genome P (n= 11); chromosomes of N. gaditanus (genome G, in white) are interspersed with those of N. ×weickertii (light grey shaded) putative of the genome G (n= 7).
