Figure 4From: Detection and mapping of homologous and homoeologous segments in homoeologous groups of allotetraploid cotton by BAC-FISHFISH photomicrographs of G. hirsutum duplicated segments hybridized to metaphase chromosomes of G. arboreum and G. raimondii. BAC clone 09D09 produced one pair of signals (arrows) on one pair of mitotic chromosomes of G. arboreum (A), but no signals on the chromosomes of G. raimondii (B).Back to article page
