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.
The shelf life of dry ice depends mainly on how the dry ice is stored and the size of the brick. Dry ice is frozen carbon dioxide, the same gas that we exhale and that plants use for photosynthesis. It is never a liquid, it goes from a -109.3Â°F solid state directly into the gas stage. Because of these properties, dry ice enjoys most of its popularity at Halloween for making a fabulous witch's brew.
