How a Guy From a Montana Trailer Park Overturned 150 Years of Biology Biology textbooks tell us that lichens are alliances between two organisms—a fungus and an alga. They are wrong.

(For simplicity, I’ll call the two fungi ascos and cyphos). The whole organism resembles a burrito, with asco fillings wrapped by a shell that’s rich in algae and cyphos.

January 24, 2017 Investigators at The Scripps Research Institute (TSRI) report the development of the first stable semisynthetic organism. Building on their 2014 study in which they synthesized a ...

In this video segment adapted from NOVA, evolutionary scientist Sean Carroll investigates why one species of fruit fly has wing spots while another genetically similar one does not. As the video ...

Therefore, a dihybrid organism is one that is heterozygous at two different genetic loci. In 1865, Gregor Mendel performed dihybrid crosses on pea plants and discovered a fundamental law of ...
