An Increase in Male Recombination Rate With Age in Dairy Cattle Is Heritable and Polygenic

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Meiotic recombination is an essential process for shuffling genetic diversity in sexually reproducing organisms, can vary within and between individuals in response to intrinsic and extrinsic factors, and can be heritable. Interestingly, recombination rate has been found to vary with age in some species, but to date, there have been no ...

Optimising the Use of Cryopreserved Genetic Resources for the Selection and Conservation of Animal Populations

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Genetic diversity is essential for the sustainability and adaptability of populations, and is thus a central pillar of the agro‐ecological transition. However, within a population, it is inevitable that some amount of genetic variability is lost, and efforts must be made to limit this as much as possible.

Effect of heterozygosity, ploidy and incubation temperature on post‐cranial axial skeletal meristics and deformities in Atlantic salmon (Salmo salar)

Journal of Fish Biology, EarlyView.
Abstract The teleostean post‐cranial axial skeleton is a highly specialized structure for an aquatic mode of life. However, there is limited knowledge regarding parental contributions, early‐life environmental impacts on its meristic variation and if reduced heterozygosity challenges its development.

Gaining insights into epigenetic memories through artificial intelligence and omics science in plants

Journal of Integrative Plant Biology, EarlyView.
This review explores how artificial intelligence and machine learning predict plant behavior in response to environmental stress by modeling molecular regulatory networks of plant stress responses. Their combined application with omics methods opens new avenues in understanding the functioning of plant memory and future plant memory‐based plant ...
