Caridina and Neocaridina gene and lineage trees

Tree 1 — taxonomy, not a completed molecular phylogeny

This outline shows genus membership and several named species, NOT a resolved branching order. Recent phylogenetic work challenges traditional Atyidae groups.

Atyidae (freshwater shrimp family)
  |-- Neocaridina (Kubo, 1938)
  |     |-- N. davidi [red/blue/orange/yellow trade lines]
  |     +-- N. denticulata [different named species]
  +-- Caridina (H. Milne Edwards, 1837)
        |-- C. logemanni [Bee shrimp]
        |-- C. mariae [Tiger shrimp]
        |-- C. conghuensis [2014 description]
        |-- C. dennerli [Lake Matano endemic]
        +-- C. multidentata [Amano shrimp]
(Indentation is categorical, not a DNA branching topology.)

• Taxonomic genus authority Caridina 1837
• Taxonomic genus authority Neocaridina 1938
• Primary 2014 formal Caridina logemanni/mariae/conghuensis taxonomy
• Broad Atyidae phylogeny shows taxonomic uncertainties

Tree 2 — reported hobby breeding routes

These arrows indicate selective breeding or reported crossings, and DO NOT authenticate a particular colony or establish a common global founder.

Neocaridina davidi (wild-type ancestry)
  |-- selected red families -> Red Cherry -> Sakura / Fire / Painted Fire
  |                              +-> Red Rili -> Blue Jelly (reported in some stock)
  |-- selected dark families -> Chocolate / Black Rose / Carbon Rili
  |                              +-> Blue Dream / Blue Diamond (claimed paths vary)
  +-- other selected families -> Yellow / Orange / Green (independent histories)

Caridina ornamental breeding complexes
  |-- Bee selections (logemanni-related) -> Crystal Black / Crystal Red / PRL
  |-- Tiger selections (mariae-related) -> Tiger color/eye variants
  +-- Bee x Tiger = Tibee [IF actual parents documented]
                   +-> crosses with Taiwan Bee = TaiTibee [breeder term]
                               +-> Pinto / Galaxy / Fishbone / Boa [multiple possible routes]
Separate wild groups: C. dennerli, C. multidentata: NOT in this designer tree.

• Specialist keeper report of Blue Jelly, Red Rili and line-cross observations; not molecular proof
• Specialist historical report on Crystal Red founder and selective lines
• Historical competition classes and named results; not a pedigree record

Tree 3 — evidence and inheritance

Parent stock authentication -> labeled paired mating -> F1 phenotype counts -> replicated F2/backcross counts -> genotype/locus assay -> independent replication. A 3:1 Mendelian phenotype expectation only applies to an adequately established single-locus dominant/recessive model; market color names alone do not meet that condition.
