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 ...
Scientists use tools like Punnett squares to predict how traits are passed from parents to offspring. Features like freckles and eye color are examples of these traits. Learn how scientists use plant ...
