Genetic Parameters for Novel Feedlot Profitability‐Related Traits in Nelore Cattle

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT This study aimed to estimate (co)variance components and genetic parameters for accumulated profitability (AFP) and profit per kilogram of liveweight gain (PFT), and their relationships with weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at first calving (AFC), probability of precocious calving at 30 ...

Biparental inbreeding depression, genetic relatedness and progeny vigor in a wind-pollinated treeline species in Argentina [PDF]

open access: yes, 2009
Spatially restricted gene flow and resulting spatial genetic structure are generally considered as being the primary controlling factors in the dynamics of biparental inbreeding depression in a wide range of plant species.

Isolation and characterization of microsatellite loci from two inbreeding bark beetle species (Coccotrypes) [PDF]

open access: yes, 2003
We developed 14 microsatellite markers in Coccotrypes carpophagus and 14 in C. dactyliperda. These loci will be used for studying genetic structure and the level of inbreeding in populations in the Canary Islands and Madeira.

Impact of Model Parameterisation and Variance Component Estimates on Genomic Predictions of Carcass Traits in Montana Composite Cattle

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT This study evaluated the influence of variance component (VC) estimates, obtained from different models and two relationship matrices, pedigree‐based (BLUP) and genomic information‐based (ssGBLUP), on genomic predictions of carcass traits in Montana composite cattle.

Improved computation of genomic and pedigree inbreeding and relationships accounting for the X chromosome

open access: yesJournal of Dairy Science
: Breeders for many decades used pedigrees to limit increases in inbreeding, but genomic measures of relationship and inbreeding provide more precise control.

Chickens First\ud \ud Speciation by “Hopeful Monsters” in Fraternal Supertwins\ud [PDF]

open access: yes, 2008
The idea of “hopeful monster” was proposed by Goldschmidt who envisioned that speciation could occur instantaneously via major chromosomal rearrangement in a one-step process; but he could not unravel how similar individual in the opposite sex to appear ...

Genome sequence and analysis of the tuber crop potato [PDF]

open access: yes
Potato (Solanum tuberosum L.) is the world’s most important non-grain food crop and is central to global food security. It is clonally propagated, highly heterozygous, autotetraploid, and suffers acute inbreeding depression.

GENOMIC AND PEDIGREE-BASED INBREEDING IN SLOVAK SPOTTED CATTLE

open access: yesAGROFOR, 2019
The objective of this study was to evaluate the level of inbreeding in population ofSlovak Spotted cattle and to compare its genomic and pedigree-based estimates.The genomic data have been obtained from in total of 37 AI sires and 50 sire damsgenotyped by using Illumina BovineSNP50v2 BeadChip and ICBF InternationalDairy and Beef v3, respectively.

Genomic Prediction Ability Using Linear and Threshold Approaches for Different Stayability Definitions in Nellore Females

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Enhancing female longevity through regular calvings improves herd replacement rates and reduces the costs associated with replacing low reproductive efficiency animals. Stayability (STAY), defined as a cow's ability to remain productive in the herd, is a categorical trait that challenges traditional genetic evaluation due to its non‐normal ...

Genomic Analysis of Inbreeding Depression on Productive Traits in Rubia Galega Beef Cattle Breed

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In autochthonous livestock breeds with small populations, such as the Rubia Galega from Galicia (Spain), mating between relatives is common and can lead to inbreeding depression. Genomic inbreeding coefficients were estimated for 4984 animals using ~63,000 SNPs to assess inbreeding depression in four key traits: age at first calving (AFC) with
