Parents or study design

Blue Jelly × Blue Dream, sometimes red-family and dark-family stocks

Recorded results

Authors report variable blue/rili/carbon/wild-looking F1/F2 and more wild-like offspring under unselected further generations

Numerical counts and denominator

Qualitative F1/F2; no reliable observed denominators

Claims requiring caution

No valid fixed ratio

Important limitations

Shared commercial blue color does NOT imply one pedigree; grade/eye/shell tissue effects can confound observed ratios.
