Signature of Selection Analysis Reveals Candidate Genes Related to Climate Adaptation and Production Traits in Lao Native Goats

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Detecting selection footprints offers valuable insight into evolutionary processes and the mechanisms underlying phenotypic diversity in selected traits. Domestication, natural and artificial selection, and breeding have produced indigenous goats well‐adapted to their local environments, making them crucial genetic resources. Understanding the

Non‐invasive ultrasound measurements for determination of hepato‐somatic index in Greenland halibut (Reinhardtius hippoglossoides)

Journal of Fish Biology, EarlyView.
Abstract Hepato‐somatic index (HSI) is widely used to indicate fish body condition and level of energy reserves related to feeding/physiology and reproduction. HSI is traditionally obtained by dissection and measurement of liver mass versus body mass, but ultrasound technology may provide a minor invasive method to obtain liver dimensions to estimate ...

3D Genome Constrains Breakpoints of Inversions That Can Act as Barriers to Gene Flow in the Stickleback

Molecular Ecology, EarlyView.
ABSTRACT DNA within the nucleus is organised into a well‐regulated three‐dimensional (3D) structure. However, how such 3D genome structures influence speciation processes remains largely elusive. Recent studies have shown that 3D genome structures influence mutation rates, including the occurrence of chromosomal rearrangement.

A Chromosome Inversion Creates a Supergene for Sex and Colour in Lake Malawi Cichlids

Molecular Ecology, EarlyView.
ABSTRACT Cichlid fishes have the highest rates of evolutionary turnover of sex chromosomes among vertebrates. Many large structural polymorphisms in the radiation of cichlids in Lake Malawi are associated with sex chromosomes and may also carry adaptive variation.
