Chromosome evolution of family Belontidae Fishes in
family Belontidae are member of order Perciformes. Most
of fishes in order Perciformes have diploid chromosome
number (2n)=48 and all chromosomes exhibited as telocentric.
As such, all ancestor chromosomes could be
telocentric with 2n=48 [11]. For the family Belontidae,
there are only 16 of all 46 species that have the
cytogenetic information. They have been distributed only
in South East Asia, India, Pakistan and Korea. Of all the
fifteen species found in Thailand, seven have been
investigated for their chromosomal details. The species
in family Belontidae show a variable chromosome
number ranging from 2n (diploid) = 16 to 2n=48,
however most show 2n=46 and 2n=48 which could be
