In this study we have mapped newly identified rDNA loci in Gossypium hirsutum. Four new minor 18S-26S rDNA loci, in addition to the sites previously identified, were mapped using fluorescence in situ hybridization (FISH) to heterozygous translocation (NT) quadrivalents (IVs). The newly detected 18S-26S rDNA loci were mapped to the right arms of chromosomes(More)
Most simple reciprocal translocation homozygotes and heterozygotes are euploid, and normal in genotype. However, translocation heterozygotes form six types of numerically balanced meiotic products. The cross of a translocation heterozygote with a normal individual can yield normal progeny, translocation heterozygotes, or any of four segmentally aneuploid(More)
