Genomic Evaluation of Recombination in Small Highly Inbred Beef Cattle Populations

Animal Research and One Health, EarlyView.
The study characterizes recombination in small beef cattle populations, revealing higher rates in CGC composites compared to inbred Line 1 Herefords. It identifies significant SNP associations linked to recombination across various autosomes, highlighting complex polygenic influences, with implications for genetic diversity and breeding strategies ...

Genome‐wide scan for selective sweeps identifies novel loci associated with resistance to mastitis in German Holstein cattle

Journal of Animal Breeding and Genetics, Volume 140, Issue 1, Page 92-105, January 2023., 2023
Abstract Domestication and selection significantly changed phenotypic and behavioural traits in modern domestic animals. In this study, to identify the genomic regions associated with mastitis, genomic data of German Holstein dairy cattle were analysed. The samples were genotyped using the Bovine 50 K SNP chip.

Relationship between inbreeding and milk production traits in two Italian dairy sheep breeds

Journal of Animal Breeding and Genetics, Volume 140, Issue 1, Page 28-38, January 2023., 2023
Abstract The effects of inbreeding in livestock species breeds have been well documented and they have a negative impact on profitability. The objective of this study was to evaluate the levels of inbreeding in Sarda (SAR, n = 785) and Valle del Belice (VdB, n = 473) dairy sheep breeds and their impact on milk production traits.

Pod and Seed Trait QTL Identification To Assist Breeding for Peanut Market Preferences

G3: Genes, Genomes, Genetics, 2020
Although seed and pod traits are important for peanut breeding, little is known about the inheritance of these traits. A recombinant inbred line (RIL) population of 156 lines from a cross of Tifrunner x NC 3033 was genotyped with the Axiom_Arachis1 SNP ...

A robust QTL mapping procedure [PDF]

Journal of Statistical Planning and Inference, 2009
In quantitative-trait linkage studies using experimental crosses, the conventional normal location-shift model or other parameterizations may be unnecessarily restrictive. We generalize the mapping problem to a genuine nonparametric setup and provide a robust estimation procedure for the situation where the underlying phenotype distributions are ...

A Comparison of Methods to Estimate Additive–by–Additive–by–Additive of QTL×QTL×QTL Interaction Effects by Monte Carlo Simulation Studies

International Journal of Molecular Sciences, 2023
The goal of the breeding process is to obtain new genotypes with traits improved over the parental forms. Parameters related to the additive effect of genes as well as their interactions (such as epistasis of gene–by–gene interaction effect and additive–by–additive–by–additive of gene–by–gene–by–gene interaction effect) can influence decisions on the ...

Shennong 1 Chicken 40K Liquid Chip: Advancing Genetic Research in Chinese Indigenous Chickens

Animal Research and One Health, EarlyView.
Based on comprehensive genomic data of Chinese indigenous chickens, we developed a specialized genotyping array for this population. Comparative analyses with published mainstream arrays and evaluations, including genetic assessment of diverse chicken types and gene mining analyses, demonstrated its superior applicability to Chinese indigenous chickens.

From Many, One: Genetic Control of Prolificacy during Maize Domestication [PDF]

PLoS Genetics 2013 9(6): e1003604, 2013
A reduction in number and an increase in size of inflorescences is a common aspect of plant domestication. When maize was domesticated from teosinte, the number and arrangement of ears changed dramatically. Teosinte has long lateral branches that bear multiple small ears at their nodes and tassels at their tips.
