Neocaridina davidi — 1,191-offspring controlled pedigree Neocaridina davidi · Known-family quantitative genetic study
GENETICS EVIDENCE
Counts are not color alleles. Measured brood counts, behavior pedigrees, pigment assays, and hobby crossing predictions describe different endpoints. No F2 color ratio should be claimed without a dated parent cohort, a clear phenotype rubric and an observed numerator/denominator.

41 groups at initiation, one male/four females each; 396 adults total including replacements; females isolated to make recorded full-sibling cohorts then 1191 offspring in 75 full-sibling families nested within 37 paternal half-sibling groups, behavioral plasticity endpoints then 1,191 offspring; 75 full-sib families; 37 paternal half-sibships; F2 deliberately removed SOURCE / PARENT DESIGN 41 groups at initiation, one male/four females each; 396 adults total including replacements; females isolated to make recorded full-sibling cohorts RECORDED INTERMEDIATE 1191 offspring in 75 full-sibling families nested within 37 paternal half-sibling groups, behavioral plasticity endpoints RESULT / CLAIM 1,191 offspring; 75 full-sib families; 37 paternal half-sibships; F2 deliberately removed Solid = source-described measurement or study design. Evidence flow; not a color-strain genotype tree. Parents or study design 41 groups at initiation, one male/four females each; 396 adults total including replacements; females isolated to make recorded full-sibling cohorts
Recorded results 1191 offspring in 75 full-sibling families nested within 37 paternal half-sibling groups, behavioral plasticity endpoints
Numerical counts and denominator 1,191 offspring; 75 full-sib families; 37 paternal half-sibships; F2 deliberately removed
Claims requiring caution None
Important limitations Offspring numbers are REAL, but experiment measures shy-bold behavior and predator cue response, not Cherry/Blue Dream alleles or F2 commercial color segregation.
