This discrepancy is most likely due to the tetraploidy of the zebrafish genome and compensation by redundant paralogs (Luo et al.
Tetraploid hybrids are easier to produce, are more fertile and tetraploidy may enhance intergeneric recombination as well as mitigate selection pressures, if any, that could operate against some combinations of chromatin from the two parental genera.

Independent events of tetraploidy may have anciently occurred in separate clades, as delineated by mitochondrial DNA criteria (Romano and Palumbi 1996), or more recently in multiple family lineages, giving rise to distantly related species bearing the same tetraploid somatic chromosome number of 28.
Polyploid oysters can lose chromosomes de novo and can even revert from triploidy to diploidy or from tetraploidy to triploidy (Allen et al.
Association mapping may be a more sensible approach than linkage analysis, although it too will be complicated by tetraploidy and by relatively low marker density.
