In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don’t completely follow ...

Basic concepts in quantitative genetics, including Mendelian genetics, gene action (additive, dominant, recessive), heritability, liability threshold model, means, variances, structure of DNA, types ...

Parents pass their genes down to their kids, with a child inheriting about 50% of their genome from each parent. But there is another kind of genetic code known as the epigenome that can also be ...

Introduction to Mendelian randomization, the problems with using traditional observational studies to investigate causality, and Randomized controlled trials as the gold standard for causal research.

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 ...

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 ...

A collaborative research team has developed a plant gene drive system called CRISPR-Assisted Inheritance utilizing NPG1 (CAIN), which, according to the researchers, uses a toxin-antidote mechanism in ...

A major mouse study found that some inherited traits are passed down through epigenetic changes that break the classic rules of genetics. Researchers discovered hundreds of cases where these chemical ...

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 new international study challenges the century‑old dominance of Mendelian genetics, arguing that most traits arise from complex interactions among many genes rather than single gene–trait links.
