Question
match these terms with definitions provided:
-genome wide association mapping GWA
-quantative genetics
-selection differential (S)
J The proportion of the total phenotypic variance of a trait that is attributable to genetic variance, where genetic variance is represented in its entirety as a single value (i.e.. on mapping genetic variance is not broken down into different components) ity (m)pb. The proportion of the total phenotypic yariance of a trait attributable to the addithe effects of alleles (the additive genetic variance). This is the component of variance that causes offspring to resemble their parents, and it causes populations to evolve predictably in response to selection. RTLs) The pattern of phenotypic expression of a single genotype across a range of environments. In a sense, reaction norms depict how development maps the genotype into the phenotype as a function of the environment d. A statistical measure of the dispersion of trait values about their mean. This process involves of scanning through the genomes of many different individuals, e. some with, and others without, a focal trait of interest, to search for markers associated with expression of the trait. f. Stretches of DNA that are correlated with variation in a phenotypic trait. These regions contain genes, or are linked to genes, that contribute to population differences in a phenotype 8. The study of continuous phenotypic traits and their underlying evolutionary mechanisms A measure of the strength of phenotypic selection. The selection differential describes the difference between the mean of the reproducing members of the population who contribute offspring to the next generation and the mean of all members of a population. h.
Explanation / Answer
Answer GWAS :- It is genome wide association study is an observable study of genome wide set of genetic variants in different individual to see if any variant is associated with trait.
Quantitative genetics:- It is a branch of population genetics that deals with phenotype that vary continuosly as opposed to discretely identifiable phenotype and gene product.
Selectional differential is the difference of the base population mean and mean of selected parents.
