We show here that these loci are unlinked to each other. In addition, gene-centromere distances were determined for these loci by analysis of halftetrads obtained by the inhibition of the second meiotic division. The fractions of tetratype (second-division segregation) tetrads range from 0.24 (spa-1) to 0.89 (gol-1). The observation of >0.67 second-division segregation indicates that the zebrafish has high chiasma interference.
