Publisher Summary Analysis of the zebrafish gene map suggests that during the course of
vertebrate evolution, the zebrafish and human lineages have shared two rounds of whole
genome duplication, and a third whole genome duplication event probably occurred before
the teleost radiation. For many genes in humans, there may be two copies in zebrafish, and
for many human chromosome segments, zebrafish is likely to have two such segments. The
haploid zebrafish genome has 25 chromosomes, most of which are difficult to distinguish …
