Uchiyama et al. question heritability estimates in a convincing manner. We offer additional arguments to further bolster their claims, highlighting methodological issues in heritability coefficients' derivation, their misuse in various contexts, and their potential contributions to exacerbating common erroneous intuitions that have been shown to lead to deleterious social phenomena. We conclude that science should move away from using them.

Qingyuan Partridge chickens represent a notable breed of high-quality, slow-growing chickens. The cost of feed constitutes 65-70 % of the total breeding expense for Qingyuan Partridge chickens. Enhancing feed utilization efficiency and reducing feed consumption are crucial for the advancement of Qingyuan Partridge chickens and the broader poultry industry.

Background: Alzheimer's disease (AD) has both genetic and environmental risk factors. Gene-environment interaction may help explain some missing heritability. There is strong evidence for cigarette smoking as a risk factor for AD.

Background: Many independent studies have found rare variants associated with AD. Current gene-based tests for rare-variants generally consider the impact of low-frequency coding variants as an independent effect from the common regulatory variants that surround them. In this work, we propose to increase the statistical power of kernel-based rare-variant association tests by accounting for the surrounding cis-regulatory variants' effects on gene expression.

Background: Subjective Cognitive Complaints (SCCs) can often precede mild cognitive impairment and dementia longitudinally. While increasingly considered an early prodromal stage of dementia, SCCs can also be a symptom of depression. Previous research found that SCCs in the absence of cognitive impairment, controlling for symptoms of depression, were moderately heritable and genetically associated with memory.

Background: Alzheimer's Disease (AD) is a common neurodegenerative disorder affecting >35 million people worldwide. Despite extensive genetic studies, the identified factors only explain a small fraction of the heritable risk of AD. This suggests the contribution of yet-unknown genetic factors to the development of AD, such as tandem repeats (TRs).
