Table 1. Tidal Volume percent increment (ΔTV%) in response to 6% CO₂ in RCF and normally-reared (CT) pups at postnatal day 16–20: Mean Values, Genetic Variance, and Heritability figures estimated from unrelated, half-sib and full-sib individuals.

	CTfs/hs	RCF_fs/hs
Mean ΔTV% response to 6% CO₂-enriched air	34.79±14.63	42.50±17.43^*
Genetic Variance for ΔTV% response to 6% CO₂-enriched air	60.01	125.25^†
Heritability for ΔTV% response to 6% CO₂-enriched air	0.21	0.37

Fs = Full sibs; hs = Half-sibs.

*Nested ANOVA: ‘postnatal treatment RCF vs. CT ’ : F_1,112 = 8.29, p = 0.0048; ‘sibship’: F_14,112 = 2.17, p = 0.01.

^†

Bartlett χ² = 8.3, p = 0.004 by Variance component analysis.

Heritability was calculated on the basis of half-sibs'correlations.
