Classical genetics

Genetic recombination

... process by which alleles at two genes in a linkage group can become separated. In this process ... is less than if they were farther apart. Genetic linkage describes the tendency of genes to be inherited ... result of their location on the same chromosome. linkage disequilibrium describes a situation in which ...

Gregor Mendel

... Erich von Tschermak . His results were quickly replicated, and genetic linkage quickly worked out. However, a period of tense argument ensued over its ... censored his results, otherwise he would have stumbled across genetic linkage . The standard botanical author abbreviation Mendel is applied to ...

Hardy-Weinberg principle

... 1 Assumptions 2 Causes of deviation 3 Derivation 4 Sex linkage 5 Generalizations 5.1 Generalization for more than two alleles ... in which case, equilibrium is reached in two generations. Sex linkage Where the a gene is sex-linked , the heterogametic sex (e.g. males in ...

Chromosomal crossover

... be expected to cross over three or four times during meiosis. This aids evolution by increasing independent assortment, and reducing the genetic linkage between genes on the same chromosome. The physical basis of crossing over was first demonstrated by Harriet Creighton and Barbara McClintock in ...

DNA

... it is far from certain that the B-form double helix is the dominant form in living cells. Direction of DNA strands The asymmetric shape and linkage of nucleotides means that a DNA strand always has a discernible orientation or directionality. Because of this directionality, close inspection of a ...

Phospholipid

... can be formed from an activated diacylglycerol or an activated alcohol. Phosphatidyl serine and phosphatidyl inositol are formed from a phosphoester linkage between the hydroxyl of an alcohol ( serine or inositol ) and cytidine diphosphodiacylglycerol (CDP-diacylglycerol). In the synthesis of ...

Trait

... were based on clear-cut traits with simple dominance. He determined that the heritable units, he called "genes", occurred in pairs and could exhibit linkage . His tool was statistics : long before the molecular theory of DNA . Biochemistry of dominance and extensions to expression of traits The ...
