Y1 - 2017 N1 - T2 - Medical Genetics: An Integrated Approach AB - The study of human inheritance often tends to focus on relatively simple traits. But as we explored in Chapter 2 and elsewhere, there is a broad avenue of molecular and developmental events that connect the DNA with a phenotype. When the work of Gregor Mendel was "rediscovered" in 1900, various researchers attempted to repeat and confirm his observations using a variety of plants and animals, including humans. Some studies supported the Mendelian genetic models. But many other cases were unsuccessful either because the organisms they chose had unusual genetic characteristics, like honeybee drones that are haploid, or because the traits they looked at did not have the simple phenotypic basis that we see in those studied by Mendel. Some people attribute these latter studies to bad luck in choosing an experimental system. But in fact they were setting the stage to explore a parallel, and very important, dimension of genetic complexity.
