Abstract Variegated patterns on the caudal fin are a common and popular trait in guppy strains commercially cultured in Singapore. Gene control of this highly variable mosaic pattern of black spots and patches of different shapes and sizes on a brightly colored tail fin was elucidated by reciprocal crosses between the Green Variegated (GV) strain and wild-type (WT) stock. F1 progenies were produced by single-pair crossing between GV and WT, while the F2 generation was obtained from full-sib… 
Sex-Linkage of the Black Caudal-Peduncle and Red Tail Genes in the Tuxedo Strain of the Guppy, Poecilia reticulata
TLDR
Gene control of the black caudal-peduncle and red tail color patterns was elucidated by reciprocal crosses between the Tuxedo (TUX) strain and wild-type (WT) stock.
Linkage Analysis and Mapping of Three Sex-Linked Color Pattern Genes in the Guppy, Poecilia reticulata
TLDR
Three phenotypic color pattern genes of the guppy, i.e., black caudalpeduncle, red tail (Rdt) and variegated tail patterning (Var), were genetically analyzed and mapped to determine the gene control of these color patterns.
Genetic linkage map of the guppy, Poecilia reticulata, and quantitative trait loci analysis of male size and colour variation
TLDR
The linkage data is used to predict quantitative trait loci for a set of variable male traits including size and colour pattern and to facilitate the advancement of genetic studies for a wide variety of complex adaptive phenotypes relevant to natural and sexual selection in this species.
Evolution of MHC class IIB in the genome of wild and ornamental guppies, Poecilia reticulata
TLDR
It is suggested that the same allele is fixed at duplicated MHC DAB loci owing to gene conversion, and the number of loci in the ornamental strains has contracted during >100 generations in captivity, a hypothesis consistent with the accordion model of MHC evolution.
Genetic Diversity Within and Among Feral Populations and Domesticated Strains of the Guppy (Poecilia reticulata) in Singapore
TLDR
Paired genetic distances analyzed by unweighted pair-group method with arithmetic means revealed distinct clustering of guppy individuals into their respective populations and strains, and principal coordinate analysis differentiated the 6 feral populations from the 2 cultured strains.
Interaction between the Autosomal Recessive bar Gene and the Y-Linked Snakeskin Body (Ssb) Pattern Gene in the Guppy, Poecilia reticulata
TLDR
Results of single-pair reciprocal matings of the Yellow Snakeskin variety show that a single gene is responsible for the vertical bar pattern, which is autosomal recessive and not expressed when the dominant allele, bar+, is present.
Linkage Mapping of AFLP and Microsatellite DNA Markers with the Body Color- and Sex-Determining Loci in the Guppy (Poecilia reticulata)
TLDR
A total of 35 linkage groups for the guppy were constructed using 186 polymorphic loci of AFLP and microsatellite DNA, and the locus related to the yellow body color was linked with ten markers and the sex-determination locus was link with five markers.
Sex Chromosomes and Sexual Selection in Poeciliid Fishes
We propose that the evolution of female preferences can be strongly influenced by linkage of attractive male traits to the Y chromosome and female preferences to the X chromosome in male
The Phenotypic Expression of Purple Body (Pb) in Domestic Guppy Strains of Poecilia reticulata
TLDR
Photographic evidence demonstrates that Purple Body is a normal polymorphism in domestic guppies modifying color pigmented regions.
Genetic Linkage Maps of the Guppy (Poecilia reticulata): Assignment of RAPD Markers to Multipoint Linkage Groups
TLDR
These primary linkage maps are the initial step toward the construction of a composite high-density map to facilitate map-based cloning and marker-assisted selection of quantitative trait loci that are essential for the development of comprehensive breeding programs for the guppy.

TLDR
The viviparous Poecillid guppyi, Lebistes re-ticulatus, native to Trinidad and the northeast coast of South America and well known to fish fanciers, has proven nearly ideal for this purpose and has shown in a series of papers that inheritance behaves as though of the XY type in this species.
