A monosome was identified as chromosome 7 of the A genome of the tetraploid cottons by its linkage with the Lc1yg2R2 markers. This makes eight chromosomes of the tetraploids now identified by monosomes. For over a decade the N locus has been considered to be linked with the Lc1yg2R2 loci. Monosomic analysis, however, reveals that N is on a separate chromosome. Studies with a telocentric of chromosome 7 show that the Lc1yg2R2 loci are located in the long arm. It is suggested that the R2 locus rather than the Lc1 locus is in the proximal position. These findings are discussed in relation to data, particularly that involving the linkage group, which supposedly illustrate the compensatory recombination phenomenon in cotton.
