Full Length Research Paper
Abstract
Chromosome counts from natural populations of Abrus pulchellus in Nigeria were carried out. Tetraploid (2n = 44) chromosome number was constant in all the samples investigated. The 44 chromosomes fall into three cytomorphological categories: eight metacentric and eight sub-metacentric pairs, and six acrocentric pairs. The chromosomes are relatively small in length ranging from 0.5 to 1.4μm. The polyploid (tetraploid) cytotype is reported for the first time for this taxon.
Key words: Abrus pulchellus, acrocentric, chromosome counts, metacentric, polyploid, sub-metacentric.
