Supporting long‐term sustainability of ex situ collections using a pedigree‐based population management approach

open access: yesApplications in Plant Sciences, 2022
Premise Living collections maintained for generations are at risk of diversity loss, inbreeding, and adaptation to cultivation. To address these concerns, the zoo community uses pedigrees to track individuals and implement crosses that maximize founder ...

Genetic evaluation of Ethiopian Boran cattle and their crosses with Holstein Friesian in central Ethiopia: milk production traits

open access: yesAnimal, 2009
Breed additive and non-additive effects, and genetic parameters of lactation milk yield (LYD), 305-day milk yield (305YD), lactation length (LL), milk yield per day of lactation (DM) and lifetime milk yield (LTYD) were estimated in Ethiopian Boran cattle

SimpleMating: R‐package for prediction and optimization of breeding crosses using genomic selection

open access: yesThe Plant Genome
Selecting parents and crosses is a critical step for a successful breeding program. The ability to design crosses with high means that will maintain genetic variation in the population is the goal for long‐term applications.

Genetic effects on carcass traits in F1 cockerels from reciprocal crosses of Fayoumi and two exotic chicken breeds

open access: yesJournal of Agriculture and Food Research
This study examined the genetic basis of carcass traits in F1 cockerels produced through reciprocal crosses between the tropically adapted Fayoumi (FM) breed and two exotic breeds: dual-purpose Koekoek (KK) and layer-type White Leghorn (WL).

Usefulness Criterion and Post-selection Parental Contributions in Multi-parental Crosses: Application to Polygenic Trait Introgression

open access: yesG3: Genes, Genomes, Genetics, 2019
Predicting the usefulness of crosses in terms of expected genetic gain and genetic diversity is of interest to secure performance in the progeny and to maintain long-term genetic gain in plant breeding.

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.

GENETIC RECOMBINATION IN SEXUAL CROSSES OF PHYCOMYCES

open access: yesGenetics, 1975
ABSTRACT Sexual crosses between strains of Phycomyces blakesleeanus, involving three auxotrophic and one color marker and yielding a high proportion of zygospore germination, are described. Samples of 20-40 germ spores from 311 individual fertile germ sporangia originating from five two-factor and three three-factor crosses were ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
