Evaluating Selection Strategies Based on Inbreeding Load via Simulation

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Inbreeding load is the fraction of the mutation load that is due to recessive action of mutations. This load is only expressed in individual's inbred offspring. As such, inbreeding load contributes to genetic heterogeneity among individuals and can thus be used as a criterion of selection.

Characterizing Runs of Homozygosity and Inbreeding in American Mink Using SNP Data and Pedigree Information

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Inbreeding increases the likelihood of deleterious recessive alleles becoming homozygous and consequently affecting economically important traits. Runs of homozygosity (ROH), the continuous homozygous segments of the genome and the higher than expected homozygosity (HOM) are genomic indicators of inbreeding, quantified as FROH and FHOM ...

Whole genome sequencing informs SNP-based breeding strategies to safeguard genetic diversity in captive African lions

Frontiers in Veterinary Science
IntroductionAfrican lions (Panthera leo) face severe population declines, making captive breeding programs essential for conservation. However, genetic data scarcity in such programs elevates inbreeding risks and threatens genetic diversity.MethodsUsing ...

Spawning behaviour between endemic delta smelt (Hypomesus transpacificus) and non‐native Wakasagi (H. nipponensis) in the San Francisco estuary

Journal of Fish Biology, EarlyView.
Abstract In the San Francisco Estuary, non‐native Wakasagi Hypomesus nipponensis hybridize with endemic and endangered Delta Smelt H. transpacificus, and all wild‐caught hybrids have a maternal Wakasagi parent. However, the mechanisms that facilitate or impede hybridization and explain sex‐biased hybrid asymmetry between these two species remain ...

Partial Selfing Can Reduce Genetic Loads While Maintaining Diversity During Experimental Evolution

G3: Genes, Genomes, Genetics, 2019
Partial selfing, whereby self- and cross- fertilization occur in populations at intermediate frequencies, is generally thought to be evolutionarily unstable. Yet, it is found in natural populations.

The consequences of partial clonality on the spatiotemporal genetic structure of the red alga Chondria tumulosa (Ceramiales, Rhodophyta)

Journal of Phycology, EarlyView.
Abstract The relative rates of sexual versus clonal reproduction partition genetic diversity, but the quantification of these rates remains limited in natural populations. This knowledge gap is particularly acute among tropical macroalgae. Chondria tumulosa is a red macroalga that has been documented at high abundance in the three northernmost atolls ...

Effect of non-random mating on genomic and BLUP selection schemes

Genetics Selection Evolution, 2012
Background The risk of long-term unequal contribution of mating pairs to the gene pool is that deleterious recessive genes can be expressed. Such consequences could be alleviated by appropriately designing and optimizing breeding schemes i.e.

Genomic analyses of giant kelp reveal restricted connectivity across the Southern Hemisphere and striking diversity in Aotearoa (New Zealand)

Journal of Phycology, EarlyView.
Abstract The macroalga Macrocystis pyrifera (“giant” or “bladder” kelp) plays a vital role in cold‐temperate marine ecosystems but faces increasing threats from ongoing environmental change. Understanding its population diversity and connectivity is essential for predicting future range shifts and assessing the ecological consequences of such shifts in

Lifespan of companion dogs seen in three independent primary care veterinary clinics in the United States

Canine Medicine and Genetics, 2020
Background The privately owned companion dog is an emerging model in comparative medicine, notably because it shares the human environment including its risk factors, is affected by many analogous age-related diseases, receives comparable medical care ...

California's vernal‐pool mousetails (Myosurus, Ranunculaceae): Phylogenetic analysis of ddRADseq data, hybridization tests, and species delimitation

Journal of Systematics and Evolution, EarlyView.
We present the first phylogenetic analysis of the Californian species of Myosurus. Our ddRADseq analysis reveals considerably more diversity than what was recognized in recent floristic treatments. Myosurus minimus subsp. apus was found to be a rare species restricted to Southern California and northwestern Baja California.
