Heritability Estimates of Naupliar Length in Artemis franciscans Using Different Methods

摘要

Parent offspring regression and analysis of variance of full-sib data was used to estimate heritability (h~2) of naupliar length from two sub lines (SNS and BNS) of Artemia franciscana evolved from same base population. Heritabilities were estimated from each of six generations of SNS and five generations of BNS. Heritabilities pooled over generations were also estimated. The pooled estimates of h~2 from parent offspring regression in males and females were 0.2123 ± 0.0766 and 0.3885 ± 0.1108 in SNS and 0.5777 ± 0.1154 and 0.3364 ± 0.1176 in BNS. The corresponding values from full-sib data were 1.3256 ± 0.0474 and 1.1004 ± 0.0522 in SNS and 1.2580 ± 0.0583 and 1.4221 ± 0.0479 in BNS.
