Gregor Mendel's principles of inheritance form the cornerstone of modern genetics. So just what are they? When looking at the figure, notice that for each F 1 plant, the self-fertilization resulted in ...

In the first study of its kind, scientists have detected evidence that DNA may not be the only carrier of heritable information; a secondary molecular mechanism called epigenetics may also account for ...

Genetics is the study of how heritable traits are transmitted from parents to offspring. Humans have long observed that traits tend to be similar in families. It wasn’t until the mid-nineteenth ...

Genetics is fiendishly complex. We know this from decades of molecular biology, from the resulting studies on the sequencing and analysis of genomes and from our increasing knowledge of how genes ...
