Estimation of genetic parameters and relationships between type traits and milk yield of Holstein cows in Turkey

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2021
In this study, milk yield, reproductive yield, and type traits of 533 Holstein cows in the first lactation raised in 54 farms were examined. In the three-year study, phenotypic (rP) and genetic (rG) correlations between type traits and milk yield were ...

Adaptive divergence and the evolution of hybrid trait mismatch in threespine stickleback

open access: yesEvolution Letters, 2022
Selection against mismatched traits in hybrids is the phenotypic analogue of intrinsic hybrid incompatibilities. Mismatch occurs when hybrids resemble one parent population for some phenotypic traits and the other parent population for other traits, and ...

Drift versus selection as drivers of phenotypic divergence at small spatial scales: The case of Belgjarskógur threespine stickleback

open access: yesEcology and Evolution, 2019
Divergence in phenotypic traits is facilitated by a combination of natural selection, phenotypic plasticity, gene flow, and genetic drift, whereby the role of drift is expected to be particularly important in small and isolated populations.

Selection and the direction of phenotypic evolution

open access: yeseLife, 2023
Predicting adaptive phenotypic evolution depends on invariable selection gradients and on the stability of the genetic covariances between the component traits of the multivariate phenotype.

Genomic and Phenotypic Udder Evaluation for Dairy Cattle Selection: A Review

open access: yesAnimals, 2023
The traditional point of view regarding dairy cattle selection has been challenged by recent genomic studies indicating that livestock productivity prediction can be redefined based on the evaluation of genomic and phenotypic data.

Adaptive divergence in resistance to herbivores in Datura stramonium [PDF]

open access: yesPeerJ, 2015
Defensive traits exhibited by plants vary widely across populations. Heritable phenotypic differentiation is likely to be produced by genetic drift and spatially restricted gene flow between populations.

A synthesis of bacterial and archaeal phenotypic trait data [PDF]

open access: yesScientific Data, 2020
AbstractA synthesis of phenotypic and quantitative genomic traits is provided for bacteria and archaea, in the form of a scripted, reproducible workflow that standardizes and merges 26 sources. The resulting unified dataset covers 14 phenotypic traits, 5 quantitative genomic traits, and 4 environmental characteristics for approximately 170,000 strain ...

Artificial selection on phenotypically plastic traits

open access: yesGenetical Research, 1999
Many phenotypes respond physiologically or developmentally to continuously distributed environmental variables such as temperature and nutritional quality. Information about phenotypic plasticity can be used to improve the efficiency of artificial selection.

Properties of phenotypic plasticity in discrete threshold traits [PDF]

open access: yesEvolution, 2021
Forms of phenotypic plasticity in key traits, and forms of selection on and genetic variation in such plasticity, fundamentally underpin phenotypic, population dynamic, and evolutionary responses to environmental variation and directional change. Accordingly, numerous theoretical and empirical studies have examined properties and consequences of ...
