Chromosomes of the Chocolate Gourami: A Cytogenetic Anomaly

Chromosomes of the Chocolate Gourami: A Cytogenetic Anomaly

The chocolate gourami, Sphaerichthys osphromonoides, has the lowest chromosome number reported for fishes, with 2n = 16 and n = 8. Other members of the family Belontiidae have somatic numbers of 42 to 48. Chromosome instability is demonstrated by the presence of somatic abnormalities and meiotic mul...

Zusammenfassung:The chocolate gourami, Sphaerichthys osphromonoides, has the lowest chromosome number reported for fishes, with 2n = 16 and n = 8. Other members of the family Belontiidae have somatic numbers of 42 to 48. Chromosome instability is demonstrated by the presence of somatic abnormalities and meiotic multivalents.
