:the quality or state of existing in or assuming different forms: such as. a(1) : existence of a species in several forms independent of the variations of sex. (2) : existence of a gene in several allelic forms also : a variation in a specific DNA sequence. What is a polymorphic in...

Are diamonds a result of carbon polymorphism? Yes, diamonds are a polymorphic form of carbon. 9 Can polymorphism be reversed? In some cases, yes, depending on the material and conditions. 7 Is amorphism always due to rapid cooling? Often, but not exclusively. Some materials are inherently am...
A mutation in a single gene causes the body to produce thick, sticky mucus that clogs the lungs and blocks ducts in digestive organs. What is a silent allele? A silent gene formally designates a rare (non-polymorphic, with frequency below 1%) recessive allele. Therefore, its presence can ...

This reaction is regulated by the fusion histocompatibility locus (fuhc), which encodes a single, highly polymorphic, co-dominantly expressed gene (De Tomaso et al., 2005). Although we are beginning to understand the molecular mechanisms that underlie the allorecognition process (De Tomaso et al...
Loss of heterozygosity (LOH) is a common genetic event in cancer development, and is known to be involved in the somatic loss of wild-type alleles in many inherited cancer syndromes. The wider involvement of LOH in cancer is assumed to relate to unmaskin
b. Genes cannot mutate unless they are polymorphic. c. Only heterozygous individuals are selected in natural populatio Enumerate and discuss the reasons why it is useful to determine whether a newborn baby carries a specific gene o...
The major histocompatibility complex is a large locus on vertebrate DNA containing a set of closely linked polymorphic genes that code for cell surface proteins
Strikingly, these pathogens devote a high percentage of their genomes to paralogous families of polymorphic surface molecules. This retention suggests that evasion of the immune response is the highest priority of obligate microbial pathogens and provides a strategy for identifying protective antigens for...
