A polygene is a member of a group of non-epistatic genes that interact additively to influence a phenotypic trait, thus contributing to multiple-gene inheritance (polygenic inheritance, multigenic inheritance, quantitative inheritance [1]), a type of non-Mendelian inheritance, as opposed to single-gene inheritance, which is the core notion of Mendelian inheritance.
Polymer chemistry is a sub-discipline of chemistry that focuses on the structures, chemical synthesis, and chemical and physical properties of polymers and macromolecules. The principles and methods used within polymer chemistry are also applicable through a wide range of other chemistry sub-disciplines like organic chemistry , analytical ...
In fact, the terms 'multifactorial' and 'polygenic' are used as synonyms and these terms are commonly used to describe the architecture of disease causing genetic component. [2] Multifactorial diseases are often found gathered in families yet, they do not show any distinct pattern of inheritance.
Polypropylene glycol is produced by ring-opening polymerization of propylene oxide.The initiator is an alcohol and the catalyst a base, usually potassium hydroxide.When the initiator is ethylene glycol or water the polymer is linear.
Oligogenic inheritance (Greek ὀλίγος – ὀligos = few, a little) describes a trait that is influenced by a few genes. Oligogenic inheritance represents an intermediate between monogenic inheritance in which a trait is determined by a single causative gene, and polygenic inheritance, in which a trait is influenced by many genes and often environmental factors.
The proposed Omnigenic Model is type of non-mendellian inheritance that builds off of previous research regarding the Polygenic Model and Fisher's Infinitesimal Model. Under the Polygenic Model, for traits, like height, to be continuous in a population there must be many genes that code for the trait.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
In organic chemistry, polyenes are poly-unsaturated, organic compounds that contain at least three alternating double (C=C) and single (C−C) carbon–carbon bonds. These carbon–carbon double bonds interact in a process known as conjugation , resulting in some unusual optical properties .
