Abstract

Ten (CA)nmicrosatellite simple sequence repeat (SSR) markers, 1, 2, 12, 14, 16, 18, 20, 22, 26, and 29, were used to show high chiasma interference and to determine centromere-marker map distances in the zebrafish (Danio rerio). Of these, SSR 12 exhibited no recombinant tetratypes among 175 half-tetrad embryos, placing this marker within 1 cM of the centromere of Linkage Group XVII. Fractions of heterozygous half-tetrads for the remaining nine markers ranged from 0.64 to 0.89. Of these, six recombinant fractions were more than 0.67 (P< 0.05), indicating strong chiasma interference during female meiosis in the zebrafish. Consistent with previous mapping data, SSRs 2 and 20 of Linkage Group VI were tightly linked. Half-tetrad analysis will allow the mapping of the remaining centromeres and may be useful in the mapping of new genes and mutations in the zebrafish.
