Parents or study design

Red/yellow/blue study strains and adult tissue collection; gene homologs across carotenoid, melanin and pteridine networks

Recorded results

Candidate BCO-like, GCH1, PTPS, TH, and CRCN genes show strain/tissue-specific expression and pigment contents

Numerical counts and denominator

Three biological replicates for qPCR and pteridine measurements; not F1/F2 parentage cohorts

Claims requiring caution

None

Important limitations

Expression association is NOT proof a named Blue Dream or Bloody Mary strain carries a dominant variant of these genes. Species as published is N. denticulata, not automatically N. davidi.
