Karyotype of a female AOL-like hybrid from Douro basin after (a) FISH with 5S
(red probe, hollow arrows) and (b) 45S rDNA (green probe, white arrows)
sequences, both including inset ideograms of the rDNA-bearing chromosomes (grey circle
=5S, black box
▪ =45S); (c) FISH with telomeric (TTAGGG)n
repeats and (d) CGH using AOL and PDU genomic DNA as probes. Genetic admixture
can be retrieved from non-matching bands between homologue pairs after CGH, particularly
in marker chromosomes numbers 8, 10 and 23. Bar=5 μm. A full color
version of this figure is available at the Heredity journal online.
