为了确定保护的优先顺序，科学家应该能够评估遗传变异性丧失、近亲繁殖和近亲繁殖的影响所构成的相对威胁，因为这些影响可能会产生“遗传压力”。发育不稳定(DI)被认为是应激的一个指标，可能比其他指标更敏感。然而，对于DI是否是评估遗传应激程度的准确和可靠的工具存在争议。在Lerner猜想提出50年后，关于DI和遗传应激之间的关系仍有几个悬而未决的问题。在这里，我们回顾关于DI背后机制的研究。对DI作为遗传应激指标的应用现状进行了讨论，并就如何在进化背景下获得更多关于DI潜力的知识提出了建议。
To set conservation priorities, scientists should be able to assess the relative threats posed by the effects of loss of genetic variability, inbreeding and outbreeding as these can generate ‘genetic stress’. Developmental instability (DI) has been suggested as an indicator of stress, possibly being more sensitive than other measures. However, there is controversy as to whether DI is an accurate and reliable tool for assessing the degree of genetic stress. After 50 years of the presentation of Lerner's conjecture, there are still several unresolved questions about the relationship between DI and genetic stress. Here, we review studies on mechanisms behind DI. The current status on the use of DI as an indicator of genetic stress is discussed, and suggestions are presented on how to obtain more knowledge on the potential of DI in an evolutionary context.
