“…AFP and AGY are strains of albino guppy. Albino strains are known as Real Red Eye Albino (RREA) or guppy strains that have red eyeballs [17]. This corresponds to the color of the eyeballs possessed by the AFP and AGY strains, both of which have red eyeball colors.…”

This study aims to determine the genetic relationship between four strains of guppy, albino full platinum (AFP), albino german yellow (AGY), top sword (TS) and guppy yellow cobra (GYC) using the RAPD-PCR method. This study used explorative method without experimental design and analyzed by descriptive qualitative and quantitative. The obtained genetic relationship data could be used as data reference for hybridization between strains of guppy fish that have been researched. The research was conducted in October 2020-April 2021. The three fish samples (AFP, TS and GYC) obtained from fish breeder in Cilengkrang-Bandung and AGY sample obtained from fish breeder in Tanggerang-Banten. Based on the results of amplification using OPA-03 primer (AGTCAGCCAC), four strains of guppy fish showed 30 DNA bands that included polymorphic and monomorphic bands. The AFP strains had 19 monomorphic bands, AGY had 21 DNA bands (20 monomorphic bands and one polymorphic bands), TS had 19 DNA bands (17 monomorphic bands and two polymorphic bands) and GYC had 15 DNA bands (14 monomorphic bands and one polymorphic band). Phylogenetic tree analyzed by NTSys program. It is shown between AFP and AGY strains had 95% relationship index, then between TS and GYC strains had 82% relationship index and between AFP-AGY and TS-GYC had 50% relationship index.

Modification of wild-type carotenoid orange and pteridine red coloration and spotting of male ornaments 14 in both wild populations of Poecilia reticulata (Guppies) and modern Domestic Guppy strains by the Purple Body 15 gene has long been overlooked in research articles and little understood in breeder publications. This modification is 16 commonly found in wild-type Poecilia reticulata reticulata populations from numerous collection sites and has been 17 photographed but not recognized in these collections. It is non-existent or near absent in collections taken from 18 variant populations of Poecilia reticulata wingei. We identify and determine the mode of inheritance, cellular and 19 phenotypic expression by the Purple gene in these stocks. The Purple Body color pigment modification is a distinct 20 polymorphism in wild P. reticulata reticulata populations. Its existence suggests multiple benefits that satisfy female 21 sexual selection preferences, and minimize or reduce potential predation risks. Photographic and microscopic 22 evidence demonstrated that Purple Body is a normal polymorphism in wild and domestic guppies modifying color 23 pigment regions. Purple Body is inherited as an autosomal incompletely dominant trait.

Mature Purple Body and Non-Purple Body male guppies differ from each other in several ways. Non-Purple males may have large numbers of xanthophores, erythrophores, and blue iridophores, in addition to the usual dendritic, corolla and punctate melanophores. Fewer violet iridophores are found. In contrast, homozygous Purple Body males lack collected and clustered xanthophores, although isolated single xanthophores remain. Violet iridophores and blue iridophores (violet-blue chromatophores units) abound. The dendrites of dendritic melanophores are finer and form chains with each other. Punctate and corolla melanophores in areas comprising orange ornaments are greatly reduced in number. The heterozygous Purple Body male has erythrophores similar to those of non-Purple males, but yellow pigment is reduced. The melanophores are not as greatly changed in orange ornaments. In Domestic Guppy strains, and at least in one suspected instance in wild-type, melanophore structure and populations may be further modified by one or more additional autosomal genes.
