摘要：
Although a majority of the leach Misgurnus anguillicaudatus in Japan are diploid (2n = 50), natural tetraploids (4n = 100) have been found among specimens obtained from commercial suppliers. Eggs from diploid leach were genetically inactivated by UV-irradiating eggs. Eggs fertilized with spermatozoa from normal diploids resulted in inviable haploid offspring, while those fertilized with spermatozoa from natural tetraploids gave rise to viable diploid androgenetic individuals. Uniparental nature (all-paternal inheritance) in these androgenetic individuals was confirmed by chromosome observation and aspartate aminotransferase (AAT) allozyme genotypes.
