Abstract
HEXAPLOID wheat, Triticum aestium, behaves cytologically as a diploid organism in that only bivalents are formed at meiosis. This diploid behaviour is principally the result of the activity of a gene or genes in the long arm of chromosome 5B (refs. 1–4). In the absence of this gene or genes multivalents are formed involving homoeologous chromosomes5.
