Pairing competition between identical and homologous chromosomes in diploid and tetraploid cells of rye telotrisomic plants
Pairing competition between identical and homologous chromosomes 1R has been directly analyzed in diploid–tetraploid chimeras of telotrisomic plants of rye Secale cereale by using C-bands as cytological markers. The results have shown pairing preferences either in diploid cells, with three doses of 1RS, and in tetraploid cells, with six doses. In both cases, the preferences found could be explained by differential pairing affinities between chromosomes.Key words: telotrisomic, rye, chimeras, banding (C), pairing.
