SEATTLE — Apr. 22, 2002 — Researchers at Fred Hutchinson Cancer Research Center have harnessed the power of yeast — a simple, single-celled organism crucial for brewing beer and baking bread — as a ...

The phenotype of organisms is shaped by the interaction between environmental factors and their genetic constitution. A recent study by a team of population geneticists shows that fruit flies live in ...

These activities introduce ideas about heredity, observing the differences and similarities in a population, and modeling how inheritance works. Campers can think about organisms as systems in which ...

Several discoveries have made genetic research one of the fastest developing research areas in the world today. With the understanding of genetic basis of disease there is a rapid development of ...
