Fruit fly mutants can sometimes be grisly. Ecdysteroid hormones control aspects of fly development, including molting and metamorphosis; because aberrations in these genes lead to embryos with a ghastly appearance, they have been collectively dubbed “Halloween genes.” In a study published in GENETICS, Uryu et al. investigated how the expression of these genes is regulated.…

Why study human diseases in frogs? For starters, 79% of genes implicated in human disease have orthologs in the African clawed frog Xenopus laevis. Frogs also produce hundreds of embryos that can be grown in a dish, meaning they can be manipulated in ways that are impractical on a large scale in mammals. For example,…

Archaeologists have long known how to extract millennia-old stories from a single tooth buried in an ancient ruin—and now geneticists have the tools to join them. Advances made in the last several years have enabled researchers to sequence tiny amounts of DNA preserved in very old specimens, such as the material inside a tooth from…

Whether it’s a battle over territory or a brawl over a sports game, aggressive behavior is a hallmark of the animal kingdom. The influence genetics has on aggression is undeniable—but the process of determining the genes involved has been frustratingly slow. To better understand genetic factors involved in aggression, some researchers have turned to male…

Corn feeds millions of people, and its low cost makes it particularly important in developing countries. However, it can’t be relied on as the sole source of protein for either humans or livestock because—like most cereals—corn is low in certain essential amino acids. In the 1960s, a type of corn was discovered with boosted levels of…

Every scientist is familiar with the p-value: it’s one of the most commonly used metrics in statistics to evaluate the likeliness that an observed relationship is due to chance. Typically, a cutoff is set at p=0.05, such that any p-value of greater than 0.05 means the result is deemed “not statistically significant”—a heartbreaking outcome for…

Mutations that disrupt the gene BRCA2 dramatically increase the odds of developing breast and ovarian cancer—but such mutations aren’t enough to cause cancer on their own. To turn normal cells cancerous, some of BRCA2’s genetic interactors must also mutate. In an article recently published in GENETICS, Ding et al. sought to identify some of these genes.…

The prolonged and severe seizures suffered by those with pyridoxine-dependent epilepsy (PDE) can lead to brain dysfunction and death if not treated. Standard antiepileptic drugs are typically ineffective for people with this rare genetic disorder—instead, they need high doses of vitamin B6 in the form of pyridoxine or pyridoxal 5′-phosphate. But even with this supplementation,…

Choosing a mate is hardly random. During courtship in the diploid phase of our life cycle, we often employ elaborate rituals and biological signals to attract and assess potential mates. But after that, we usually assume that eggs and sperm choose each other randomly at fertilization. Or so says Mendel’s First Law. But sometimes, Joseph…
