The advantage of association mapping is that it can map quantitative traits with high resolution in a way that is statistically very powerful. Association mapping, however, also requires extensive knowledge of SNPs within the genome of the organism of interest, and is therefore difficult to perform in species that have not been well studied or ...
A player exploring a randomly generated map in the 2016 roguelike game Nuclear Throne A randomly generated dungeon map in the 1980 videogame Rogue. In video games, a random map is a map generated randomly by the computer, usually in strategy games. Random maps are often the core of single and multiplayer gameplay, aside from story based ...
For example, the locus of gene OCA1 may be written "11q1.4-q2.1", meaning it is on the long arm of chromosome 11, somewhere in the range from sub-band 4 of region 1 to sub-band 1 of region 2. [citation needed] The ends of a chromosome are labeled "pter" and "qter", and so "2qter" refers to the terminus of the long arm of chromosome 2. [citation ...
Genetic architecture is the underlying genetic basis of a phenotypic trait and its variational properties. [1] Phenotypic variation for quantitative traits is, at the most basic level, the result of the segregation of alleles at quantitative trait loci (QTL). [2]
This gene encodes a protein that belongs to the microtubule-associated protein family. The proteins of this family were originally isolated since they copurify with tubulin in polymerization experiments: tubulin in cell extracts can be made to polymerize to produce microtubules (MT) under the influence of heat and the addition of GTP, and the MT can then be collected by centrifugation.
Genetic association is when one or more genotypes within a population co-occur with a phenotypic trait more often than would be expected by chance occurrence.. Studies of genetic association aim to test whether single-locus alleles or genotype frequencies or more generally, multilocus haplotype frequencies differ between two groups of individuals (usually diseased subjects and healthy controls).
The concept of ancestral reconstruction is often credited to Emile Zuckerkandl and Linus Pauling.Motivated by the development of techniques for determining the primary (amino acid) sequence of proteins by Frederick Sanger in 1955, [9] Zuckerkandl and Pauling postulated [10] that such sequences could be used to infer not only the phylogeny relating the observed protein sequences, but also the ...
Marker assisted selection or marker aided selection (MAS) is an indirect selection process where a trait of interest is selected based on a marker (morphological, biochemical or DNA/RNA variation) linked to a trait of interest (e.g. productivity, disease resistance, abiotic stress tolerance, and quality), rather than on the trait itself.
