Purpose: iPlant's "Genotype to Phenotype" Grand Challenge is creating computer tools to help scientists understand the complex network of genotype and environmental interactions. Deciphering this puzzle will allow us to understand and improve the phenotypes of the crops on which we rely.
Teams of scientists in the US and Mexico have independently sequenced the most complex plant genome to date. Comparison of two varieties offers insight into the early domestication of corn.
Professor Philip Shaw discusses research that indicates very few environmental factors that very directly cause ADHD, though there may be many gene-environment interactions.
Professor Allen Moore outlines the differences between quantitative genetics and linkage studies. With quantitative genetics it is not necessary to begin with the physical DNA.
