Phenotypic selection
WebPhenotypic screening is a type of screening used in biological research and drug discovery to identify substances such as small molecules, peptides, or RNAi that alter the phenotype of a cell or an organism in a desired manner.

WebJul 18, 2024 · Many phenotypic traits are themselves both under divergent selection and responsible for reproductive isolation, in which case a shared genetic basis is expected. Selection on phenotypes can also generate immigrant inviability and extrinsic selection against hybrids, whose basis is likely often to be polygenic. WebFor the selection of accessions with important and highly productive agronomic characteristics, the program R was used to analyze selection indices (RIndSel: R software to analyze Selection Indices) to obtain Smith’s linear phenotypic selection index . The following variables were weighted: yield, plant height, seed diameter and grain color ...

WebEffective selection within a group of animals over a number of generations decreases the genetic variance. The use of inbreeding as a system of mating also reduces the genetic variance. Any management practice that ensures uniform treatment of animals reduces environmental variance. WebPlant breeders always face the challenge to select the best individuals. Selection methods are required that maximize selection gain based on available data. When several crosses have been made, the BLUP procedure achieves this by combining phenotypic data with information on pedigree relationships via an index, known as family-index selection. The …
