Single gene inheritance. Single gene inheritance, also called Mendelian or monogenetic inheritance. This type of inheritance is caused by changes or mutations that occur in the DNA sequence of a single gene. There are more than 6,000 known single-gene disorders, which occur in about 1 out of every 200 births.ome examples of monogenetic disorders include: 1  cystic fibrosis, 2  sickle cell anemia, 3  Marfan syndrome, 4  Huntington's disease, and. 5  hemochromatosis.
The secret is in the chemical composition of dry ice, which is carbon dioxide in solid form. At room temperature, carbon dioxide exists as a gasâthe very gas we exhale every time we breath. But this familiar compound has some unusual physical properties.
At room temperature and pressure, carbon dioxide, or CO2, is a common gas, about 0.05 percent of the air at sea level by weight. It is also a product of combustion and the respiration of all animals. When chilled below minus 109 degrees Fahrenheit, it becomes a solid, called dry ice. Dry ice was first discovered and observed by French chemist Charles Thilorier in 1834. In 1925, the solid form of CO2 was trademarked by the DryIce Corporation of America as âDry iceâ. In the commercial production of dry ice, liquid carbon dioxide is chilled below minus 109 degrees Fahrenheit and compressed.
