SummaryWe研究了遗传力和运动性能（速度，耐力）的措施之间的相关性和可能的形态决定因素的性能（后肢跨度，尾长）在家庭的孵化蜥蜴（Sceloporus occurentalis）。我们特别感兴趣的是确定这些特征是否是可遗传的，从而可能对选择产生潜在的遗传反应。此外，我们希望确定速度和耐力是否是负相关的遗传，所建议的先验生理和经验的考虑。所有这四个特征似乎是显着遗传。速度、耐力、后肢距和尾长的广义遗传力分别为0.33-0.36、0.35-0.36、0.45-0.51和0.46-0.47。与预期相反，速度和耐力在基因上并不存在负相关。然而，后肢跨度和尾长呈负遗传相关（但不表型相关）。后肢跨度和耐力正表型相关。因此，例如，选择较长的后肢跨度可能会导致较短的尾巴，与仅基于表型相关性的进化预测相反。
SummaryWe examined heritabilities and correlations among measures of locomotor performance (speed, stamina) and among possible morphometric determinants of performance (hindlimb span, tail length) in families of hatchling lizards (Sceloporus occidentalis). We were particularly interested in determining whether these traits were heritable and thus might potentially respond genetically to selection. Moreover, we wished to determine whether speed and stamina are negatively genetically correlated, as suggested bya priori physiological and empirical considerations. All four traits appeared to be significantly heritable. Broadsense heritabilities were 0.33–0.36 for speed, 0.35–0.36 for stamina, 0.45–0.51 for hindlimb span, and 0.46–0.47 for tail length. Contrary to expectations, speed and stamina were not negatively genetically correlated. Hindlimb span and tail length, however, were negatively genetically correlated (but not phenotypically correlated). Hindlimb span and stamina were positively phenotypically correlated. Thus, for example, selection for longer hindlimb span could potentially result in shorter tails, contrary to evolutionary predictions based only on phenotypic correlations.
