... centuries scientists have always been curious as to what makes a human being human; what is it that makes each individual unique? The history of genetics can be traced back to 1866 and the work of an Augustinian friar named Gregor Mendel, who was able to prove heredity ... source of Down syndrome was discovered in the 21st chromosome referred to as trisomy 21 (O'Connor). Since then, there have been tests that allow the detection of Down syndrome before the birth of the child. Scientists will now be able to go above and beyond the currently available ...

... has the disorder or can result from a new mutation (change) in the gene. Thus, NF can occur in a person who has no family history of the condition. About 50 percent of NF1 and NF2 cases are caused by new mutations. An individual with NF caused by a new mutation ... the gene for NF1 on the 17th chromosome, and the gene for NF2 on the 22nd chromosome. Scientists are using this information to develop precise tests aimed at definitively diagnosing these disorders, even before an individual develops symptoms. Early diagnosis should allow doctors to treat symptoms sooner, possibly preventing s...

... map was created to show the location of genes. Morgan used fruit flies in his experiments because of their "simple genetic structure and rapid breeding."" (http://library.thinkquest.org/C0122429/history/history.htm). In 1928, Hans Spemann conducted the first nuclear transfer experiment. He used "salamander embryos, where he transferred the nucleus of a salamander embryonic cell into a cell with no nucleus. ... surviving tadpoles cloned from differentiated cells were abnormal, leading Briggs and King to believe that adult differentiated cells cannot be used to clone an organism.""

... environment. Mendel also correctly stated that two copies of every factor exists and that one factor of inheritance could be dominate over another. The next major events of genetic history involved the discovery DNA (deoxyribonucleic acid). DNA is a double helix of amino acids and proteins that are encode the blueprint for all living things. DNA was found ... an individual's genetic differences How does the information affect an individual, and society's perceptions of that individual? 4) Genetic testing of an individual for a specific condition due to family history (prenatal, carrier, a...

... mindset was changing from controlling others to controlling their own families. Scientists in the field of eugenics were testing procedures to screen for hemophilia and Tay-Sachs disease (NOAH). The tests for these genetically transmitted diseases could be taken by couples planning to conceive a child. The results would allow the future parents to make an informed decision whether to risk the ... - to insist that all persons undergo some kind of genetic evaluation?

... of DNA will help match organ donors with recipients with little or no chance for failure. Last but not least, scientists can use DNA to study human evolution and uncover history by examining people dead for thousands of years. 3 A second benefit coming from the study of genetic engineering would be the study and application of molecular medicine. Certain genetic technology and ... likely. Nobody will choose genes that will give his/her child abnormal feet or abnormal height. This part of genetic research can be 5 held off for quite sometime.
