Figure 5From: Meiotic and mitotic behaviour of a ring/deleted chromosome 22 in human embryos determined by preimplantation genetic diagnosis for a maternal carrier Ideogram and probe strategy to detect the ring 22/del 22 chromosome in embryonic nuclei. First round hybridization: DiGeorge-dual band probes (22q11.2 orange/22q13.3 green). Second round hybridization: Centromere 14/22 red and 14qtel in green (not shown).Back to article page
