Latest Allele Stories
For two decades, researchers have been using a growing volume of genetic data to debate whether ancestors of Native Americans emigrated to the New World in one wave or successive waves, or from one ancestral Asian population or a number of different populations.
The stickleback fish, Gasterosteus aculeatus, is one of the most thoroughly studied organisms in the wild, and has been a particularly useful model for understanding variation in physiology, behavior, life history and morphology caused by different ecological situations in the wild.
By Chaudhry, A S Kochhar, R; Kohli, K K Proton pump inhibitors (PPIs) are extensively metabolized in the liver by CYP2C19, that demonstrates genetic polymorphism with 21 mutant alleles.
By Gloria-Bottini, Fulvia Bottini, Nunzio; Magrini, Andrea; Renzetti, Gabriele; Martinoli, Roberta; Bergamaschi, Antonio; Bottini, Egidio Abstract The well-known relationship between low birth weight and allergies prompted us to investigate a possible pleiotropic effect of ACP1 on these conditions.
A newly cloned gene in corn will help explain how unusual interactions between a parent's genes can have lasting effects in future generations. The finding has implications for breeding better crop plants and unraveling complex genetic diseases.
Even if they're healthy, older people with the higher-risk genotype for Alzheimer's disease can suffer major problems with prospective memory -- the ability to remember what they need to do in the future, such as take medications or make a doctor's appointment, a new study says.
- A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
