Ova contain only X chromosomes, but sperm contain either an X or a Y in a one-to-one ratio. At fertilization, there is an equal chance of an XX or an XY pair being formed. Sex-linked characteristics, such as hemophilia, arise because there are regions of the X chromosome without corresponding regions on the smaller Y chromosome. | | | | |  | As100 Maiores Descobertas: Genética

Rules of Heredity (1850s) Austrian monk and botanist Gregor Mendel discovers how genetic information is passed down through generations. In experiments performed on pea plants, he notices that characteristics of a plant's offspring, such as height, exhibit recessive and dominant behavior. Mendel's findings are ridiculed during his lifetime and he dies never knowing that he would come to be known as the "father of genetics." 2. Genes Are Located on Chromosomes (1910 - 1920s) Thomas Hunt Morgan discovers that genes are located on chromosomes. Working on fruit flies, he concludes that certain traits are linked to gender and that those traits are probably carried on one of the sex chromosomes (X or Y). He hypothesizes that other genes are also carried on specific chromosomes. Using chromosome recombination, he and his students map the locations of genes on chromosomes. Morgan and his students write the seminal book The Mechanism of Mendelian Heredity. 3. Genes Control Biochemical Events (1930) George Beadle and Edward Tatum discover through experiments on neurospora, a bread mold, that genes are responsible for the production of enzymes. Their report is the genesis of the "one gene-one enzyme" concept. 4. Some Genes Can Jump (1940) Barbara mcclintock discovers transposons - genes that can jump on a chromosome - while seeking to explain color variations in corn. Transposons are segments of DNA that can move to different positions in the genome of a single cell.

Genetics for Epidemiologists: Applications of Human Genomics to Population Sciences, was a short course for investigators and trainees in the field of epidemiology and related population-based sciences. It was conducted by the National Human Genome Research Institute (NHGRI) on May 13-14, 2008 at Northwestern University in Chicago. The goal of Genetics for Epidemiologists (GFE) was to familiarize epidemiologists and population-based researchers with recent developments in the theory and methods of human genetics that might be applied to the study of the distribution, natural history and etiology of diseases in populations. The course consisted of eight one-hour lectures and focused on the interface between genetics and epidemiology. Emphasis was on the application of modern human genome analysis methodologies to studies of human populations through the design, conduct, analysis, and interpretation of studies which effectively answer the epidemiologic question of interest. GFE is co-sponsored by the Office of Population Genomics, NHGRI, and the Department of Preventive Medicine at Northwestern University's Feinberg School of Medicine. These videocasts are provided as an educational tool for epidemiologic investigators interested in learning more about applying genomics to their work.

Does the evidence so far help shed light on the ancient question: Is the galaxy filled with life, or is Earth just a beautiful, lonely aberration? If things dont work out on this planet Or if our itch to explore becomes unbearable at some point in the future Astronomers have recently found out what kind of galactic real estate might be available to us. Well have to develop advanced transport to land there, 20 light years away. The question right now: is it worth the trip? | | | | |  | Genetic Variation

Presented by Yi Wei and Serge Gebhardt, ETH Zurich, at the 4th Annual Google Test Automation Conference, October 21st, 22nd, 2009, Zurich, CH A random testing strategy for object-oriented software basically constructs test cases by performing the following two tasks: 1) randomly select a method under test (MUT); 2) randomly select or construct objects to feed to the chosen method as either target or arguments. Usually, all the objects that are created for or returned by a MUT are stored in an object pool so they can be reused for future test cases. When working with OO software equipped with contracts, it becomes difficult for a random testing strategy to select objects that satisfy the precondition of the MUT. As a result some methods are never tested because all generated test cases fail to satisfy their preconditions. An evaluation of the object pool showed that the traditional strategy often misses object combinations that do satisfy the muts preconditions. Therefore we keep track of these object combinations during the testing process, and directly select them for muts. We call this the smart object selection strategy. We implemented the idea in our testing tool autotest for Eiffel. We introduced a predicate pool to keep track of object combinations satisfying preconditions of a certain method. All preconditions appearing in the classes under test are <b>...</b> | | | | |  | Analysis of Genetic Association Studies
