People can, however, write contracts that specify payment in other currencies. … A more profound, and perhaps slightly unsettling, reason that a dollar has value is simply that lots of people are willing toRead More →
X-linked Inheritance: Red-Green Color Blindness, Hemophilia. Genes are inherited from our biological parents in specific ways. One of the basic patterns of inheritance of our genes is called X-linked inheritance. Is color blindness inherited from the mother or father? The most common kinds of color blindness are genetic, meaning they’reRead More →
Merle is an incompletely dominant coat color pattern characterized by irregularly shaped patches of diluted pigment and solid color. Is the merle gene rare? The merle gene is quite rare among Dachshunds, and not seen too often. It can appear in all three coat varieties: long, short and wire-haired. TheRead More →
This condition is inherited in an autosomal recessive pattern , which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms ofRead More →
Phytoplankton serve as the major primary producers in the marine ecosystem. These microscopic, single-celled plants, bacteria, algae and other organisms harvest sunlight through photosynthesis and store it as chemical energy before becoming food for tiny creatures called zooplankton. What organisms are important producers in cold water? The principal marine primaryRead More →

Background. Previous studies of families with frontotemporal dementia (FTD) support an autosomal dominant inheritance pattern, but most studies have described genetic transmission in individual families specifically selected for the presence of multiple affected individuals. Does FTD skip generations? Most cases of FTD are sporadic, meaning that there is no knownRead More →
Like many complex traits, handedness does not have a simple pattern of inheritance. … However, because the overall chance of being left-handed is relatively low, most children of left-handed parents are right-handed.
