• The Blue Snakeskin (BSS) and Red Snakeskin (RSS) varieties are popular strains commercially cultured in Singapore. The blue-black tail color of BSS guppies is determined by a dominant X-linked gene (Blt) and the silvery snakeskin pattern on the body of males is under the control of a Y-linked gene (Ssb). The Y-linked snakeskin tail pattern gene (Sst) though present in BSS males is masked by the blue-black tail color gene (Blt). The putative genotypes for males and females of the BSS variety are X_<Blt>Y_<Ssb,Sst> and X_<Blt>X_<Blt>, respectively. The red tail color of the RSS variety is due to an X-linked dominant gene (Rdt). The snakeskin body pattern of RSS males is under the control of the Y-linked Ssb gene while the black reticulations on the tail is due to interaction between the snakeskin tail pattem gene (Sst) and the red tail gene (Rdt). The proposed genotypes for males and females of the RSS variety are X_<Rdt>Y_<Ssb,Sst> and X_<Rdt>X_<Rdt>, respectively. An estimate of 0.9% crossover frequency was obtained between the Y-linked Ssb and Sst genes and a 2.7 % crossover rate of the Blt gene from the X-to the Y-chromosome.
