Key Genetic Parameters for Population Management [PDF]

Frontiers in Genetics, 2019
Population management has the primary task of maximizing the long-term competitiveness of a breed. Breeds compete with each other for being able to supply consumer demands at low costs and also for funds from conservation programs. The competition for consumer preference is won by breeds with high genetic gain for total merit who maintained a ...

Genetic parameters of color phenotypes of black tiger shrimp (Penaeus monodon)

Frontiers in Genetics, 2022
Black tiger shrimp (Penaeus monodon) is the second most important aquaculture species of shrimp in the world. In addition to growth traits, uncooked and cooked body color of shrimp are traits of significance for profitability and consumer acceptance ...

A Genetic Study on Lifetime Traits for Experimental Herds of Friesian Cattle [PDF]

Arab Universities Journal of Agricultural Sciences
This study analyzed data from 5,518 lactations involving 1,749 Friesian cows raised in two experimental herds between 1992 and 2022.  The study aim was to estimate the genetic parameters for longevity traits using a multiple-trait animal model, including

Genetic parameters for the external udder morphology in commercial farms of Istrian sheep from Croatia [PDF]

Journal of Central European Agriculture, 2019
Istrian sheep is a local breed with superior milk yield and composition. Excellent udder shape of this breed needs to be preserved in future, since it’s economic value resides within the artisanal cheese production. Genetic parameters for the teat angle (

Genetic parameters estimation for preweaning traits and their relationship with reproductive, productive and morphological traits in alpaca

Animal, 2017
The aim of this study was to estimate the genetic parameters for preweaning traits and their relationship with reproductive, productive and morphological traits in alpacas. The data were collected from 2001 to 2015 in the Pacomarca experimental farm. The

Operator and parameter adaptation in genetic algorithms [PDF]

Soft Computing, 1997
Genetic Algorithms are a class of powerful, robust search techniques based on genetic inheritance and the Darwinian metaphor of “Natural Selection”. These algorithms maintain a finite memory of individual points on the search landscape known as the “population”.

Genomic Analysis of Milk Protein Fractions in Brown Swiss Cattle

Animals, 2020
Depending on whether milk protein fractions are evaluated qualitatively or quantitatively, different genetic outcomes may emerge. In this study, we compared the genetic parameters for the major milk protein fractions—caseins (αS1-, αS2-, &

Genetic and Environmental Parameters of Milk Constituents for Five Breeds. II. Some Genetic Parameters

Journal of Dairy Science, 1968
Abstract Estimates were made of some genetic parameters of milk yield and its components and of the breeding values of sires for yields and constituent percentages. The data consisted of 1.449 cows of the Ayrshire, Guernsey, Holstein, Jersey, and Brown Swiss breeds located in 43 herds.

Loading as a design parameter for genetic circuits [PDF]

2016 American Control Conference (ACC), 2016
A significant problem when building complex biomolecular circuits is due to context-dependence: the dynamics of a system are altered upon changes to its context, potentially degrading the system's performance. Here, we study retroactivity, a specific type of context-dependence, by analyzing the effects of loads on a transcription factor applied by the ...

Selection of early lima bean lines for grain yield

Pesquisa Agropecuária Tropical
The scarcity of improved lima bean (Phaseolus lunatus L.) cultivars in Brazil has made it difficult to reach new production levels. This study aimed to select early and high-yielding lima bean lines with commercially desirable seed traits.
