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 ...

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 ...

Hair genetics can come from either parent, and multiple genes can determine hair traits, such as color, texture, and growth. Genes can also affect hair loss. Although it can run in families, this is ...

A research team has unveiled the molecular mechanism behind the fading of lilac (Syringa oblata) flowers, a long-standing mystery in ornamental plant biology. The ...

Genetic disorders can occur due to mutations in one gene (monogenic), multiple genes (multifactorial inheritance), and mutation in one or more chromosomes. Point mutations are where one nucleotide in ...

Mice show that DNA methylation tags can defy Mendel’s inheritance rules by appearing in offspring even when neither parent ...
