Population Genetics and Microevolutionary Theory, 2022 AbstractMost phenotypic traits are the product of many genes as well as environmental effects, and the resulting phenotypic variation is quantitative rather than qualitative. The extent to which traits are under genetic control is termed heritability, and can be estimated by analyzing the phenotypic similarity of related individuals.

Reinventing quantitative genetics for plant breeding: something old, something new, something borrowed, something BLUE. [PDF]
Heredity (Edinb), 2020 The goals of quantitative genetics differ according to its field of application. In plant breeding, the main focus of quantitative genetics is on identifying candidates with the best genotypic value for a target population of environments.

The International Encyclopedia of Biological Anthropology, 2013 This chapter focuses on quantitative genetics, which analyses the inheritance of complex traits. Complex traits are multifactorial: their expression is influenced by multiple genes and various environmental factors. Most complex traits exhibit continuous phenotypic variation and threshold traits exhibit just two phenotypes.

Quantitative Genetics of Food Intake in Drosophila melanogaster. [PDF]
PLoS One, 2015 Food intake is an essential animal activity, regulated by neural circuits that motivate food localization, evaluate nutritional content and acceptance or rejection responses through the gustatory system, and regulate neuroendocrine feedback loops that ...

Evolvability: A Quantitative-Genetics Perspective
Annual Review of Ecology, Evolution and Systematics, 2021 The concept of evolvability emerged in the early 1990s and soon became fashionable as a label for different streams of research in evolutionary biology.

Genetics Selection Evolution, 2023 Background Recently, crossbred animals have begun to be used as parents in the next generations of dairy and beef cattle systems, which has increased the interest in predicting the genetic merit of those animals.

Breed of origin of alleles and genomic predictions for crossbred dairy cows
Genetics Selection Evolution, 2021 Background In dairy cattle, genomic selection has been implemented successfully for purebred populations, but, to date, genomic estimated breeding values (GEBV) for crossbred cows are rarely available, although they are valuable for rotational ...

Supervised learning techniques for dairy cattle body weight prediction from 3D digital images
Frontiers in Genetics, 2023 Introduction: The use of automation and sensor-based systems in livestock production allows monitoring of individual cows in real-time and provides the possibility of early warning systems to take necessary management actions against possible anomalies ...
