For more than a century, heredity has been framed through the tidy logic of Mendel’s pea plants: traits pass from parent to ...
A major mouse study found that some inherited traits are passed down through epigenetic changes that break the classic rules ...
Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA ...

A Johns Hopkins-Texas A&M mouse study found 7% of inherited DNA methylation patterns ignore Mendel’s rules across three generations
Researchers at Johns Hopkins University and Texas A&M University have documented at least 522 autosomal sites where DNA ...
The year was 1900. Three European botanists — one Dutch, one German and one Austrian — all reported results from breeding experiments in plants. Each claimed that they had independently discovered ...
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 ...
A new study suggests that the long-standing Mendelian view of genetics has some blind spots.
Genetic information in the DNA and modifications, such as DNA methylation, define the epigenetic landscape and phenotype and show both Mendelian and non-Mendelian heredity. Scientists have long known ...
Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. “Epigenetic” marks — chemical modifications to DNA that don’t change the DNA ...
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 ...
