Trichomycterus davisi, for example, is an extreme case where the polymorphism was present within a single chimeric individual.
Genetic association studies that have uncovered the same polymorphisms in people with asthma and COPD provide support for the notion that the two conditions share some biological characteristics; implicated genes include ADAM33, CCL5 and IL17F.
#A functional polymorphism in the monoamine oxidase A (MAOA) gene promoter can moderate the association between early life trauma and increased risk for violence and antisocial behavior.
Balanced polymorphism could arise when a predator like the Song Thrush has a given 'search image', so it tends to see and kill snails of a particular colour and pattern.
Goldsmith, along with colleague Fritz Laves, first defined the crystallographic polymorphism of alkali feldspar (Newton, 1989).
on the association between the 5-HTTLPR polymorphism in the serotonin transporter gene and the personality trait neuroticism has been highly cited and was one of the first papers in personality genetics.
For many decades a long line of geneticists and botanists, including Sewall Wright, Carl Epling, and T. G. Dobzhansky, have studied populations of this flower to determine the factors that influence this polymorphism.
Other studies have associated neuroticism with genetic variations, e.g., with 5-HTTLPR — a polymorphism in the serotonin transporter gene.
Restriction Fragment Mass Polymorphism (RFMP) is a technology which digests DNA into oligonucleotide fragments, and detects variation of DNA sequences by molecular weight of the fragments.
