Descriptive phenotypic and genetic statistics for spermatheca size and shape and sperm length for O. taurus
| Trait | Mean | VP | VA | h2 (SE) | CVP | CVA |
|---|---|---|---|---|---|---|
| Centroid size | 1,005.57 | 3,552.31 | 599.30 | 0.68 (0.15) | 5.92 | 2.43 |
| RW1* | 0.00 | 4.7 × 10−3 | 3.3 × 10−4 | 0.28 (0.03) | — | — |
| Sperm length,† mm | 0.99 | 6.7 × 10−4 | 1.9 × 10−4 | 1.14 (0.47) | 2.61 | 1.39 |
VP, phenotypic variance; VA, additive genetic variance; h2, narrow sense heritability; CVP, coefficient of phenotypic variation; CVA, coefficient of additive genetic variation.
*RW scores have zero mean, precluding the calculation of coefficients of variation.
