For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its ...

The Hardy-Weinberg theorem characterizes the distributions of genotype frequencies in populations that are not evolving, and is thus the fundamental null model for population genetics. Under the ...

Data from a series of randomized trials in the United States suggests that if teachers move genetics instruction toward more complex genomics concepts, they can help students have a more ...

Mendel’s monastery garden experiments went largely unnoticed during his life, but their implications would ripple through science decades later. Gregor Mendel, Austrian botanist and founder of ...

For more than a century, heredity has been framed through the tidy logic of Mendel’s pea plants: traits pass from parent to offspring by fixed genetic rules. But a new mouse study suggests that ...
