What did Gregor Mendel think he discovered?

Article Abstract:

Gregor Mendel has long been acknowledged as the founder of genetics, but his work on the genetics of peas continues to generateboth admiration and criticism. One extreme view opines that Mendel's experiments are fictitious, and were carried out only on the pages of his notebooks. However, his writings as well as his limitations can only support the view that Mendel had a clear notion of what he was studying and its implications. He was certainly a hybridist, but was still aware of the paired nature of homozygous forms. In the end, although some aspects of his work may be flawed, Mendel deserves credit and admiration for his remarkable insights.

Cloning, inbreeding and history

Article Abstract:

The successful cloning of Dolly the lamb from the udder cell of an adult sheep in 1997 evoked similar controversy and analogy to innovative breeding techniques developed by Robert Bakewell almost 200 years ago. Bakewell's breeding techniques reduced the bone structure of sheep and doubled the weight of the meat. The impact of his work invites an interesting look at the previous attitudes of scientists and the public in light of recent cloning experiments.

Population genetics of polymorphism and divergence

Article Abstract:

A study was conducted to evaluate the application of a population genetics model to nucleotide sample configurations in the alcohol dehydrogenase gene (Adh) in Drosophila simulans and Drosophila yakuba. The model incorporates mutant site frequencies as a Poisson random field in two species sharing a common origin. Results show that the model presents a theoretical foundation for developing contingency tables to analyze polymorphism and divergence.
