Parents or study design

Three commercial diets A, B, and C to mothers, egg carotenoid and hatchling fitness compared

Recorded results

Egg carotenoid was 40% lower in B and 52% lower in C versus A; other effects depended on endpoint and some reproductive differences were not statistically significant

Numerical counts and denominator

Three diet arms; 40%/52% egg-carotenoid differences, NOT color-allele segregation percentages

Claims requiring caution

None

Important limitations

Food-linked pigmentation/provisioning is an environmental effect, not a heritable offspring color genotype. Study diet brands anonymized.
