The cytology of oxalis dispar (brown)

Chromosoma Aims and scope Submit manuscript

Summary

The chromosome complement ofOxalis dispar 2n = 12 consists of a pair of submedian (SM) chromosomes, three subterminal (ST) and seven telocentric (TE) chromosomes. At mitosis and meiosis the TE chromosomes are as efficient and stable as the other chromosomes of the complement. Chromosome breakage at the centromere in the metacentric chromosomes may give rise to new TE chromosomes. It is suggested that all the TE chromosomes may have arisen from metacentric chromosomes in this way. They may have been favoured because of the deleterious nature of the discarded chromosome arms.
