Subject:
Merino; animal genetics; meat quality; sheep; somatotropin; wool
Abstract:
... The South African Mutton Merino (SAMM), a dual‐purpose (meat and wool) sheep breed, is characterized by its excellent performance on growth, carcass traits and meat quality compared to other fine‐wool Merino breeds. Nowadays, the SAMM breed has been widely used to cross with commercial and indigenous fine‐wool or coarse‐wool breeds to improve the growth and meat performance in many countries. To d ...

Subject:
DNA; Thoroughbred; animal genetics; computer software; exons; gene expression; horses; humans; hydrolysis; polymerase chain reaction; pseudogenes; risk; transgenes
Abstract:
... Processed pseudogenes, also known as retrocopy genes, are copies of messenger RNAs that have been reverse transcribed into DNA and inserted into the genome. In this study, we identified 62 processed pseudogene candidates as intron‐less genes from whole‐genome sequencing (WGS) data of Thoroughbred horses using delly structural variation software. The 62 processed pseudogene candidates were confirme ...

Subject:
Duroc; Pietrain; alleles; animal genetics; backfat; drip loss; exons; gene frequency; genetic markers; hybrids; intramuscular fat; landraces; longissimus muscle; muscle contraction; mutants; pH; pork quality; slaughter; striated muscle; swine
Abstract:
... The TNNC2 gene encodes the fast‐skeletal C subunit of the troponin complex that plays a vital role in the regulation of striated muscle contraction and could be a candidate gene for pork quality. Here, we identified coupled insertion/deletion (indel) variants, a 17‐bp insertion and an 11‐bp deletion, in porcine TNNC2. The coupled indel variants provide an alternative splicing donor site and cause ...

Subject:
animal genetics; autosomes; backfat; body length; chest; crossbreds; estrogens; fat thickness; genotype; industry; marker-assisted selection; morphogenesis; muscles; phenotype; swine
Abstract:
... Body traits are important economic factors in the pig industry. Genome‐wide association studies (GWASs) have been widely applied using high‐density genotype data to detect QTL in pigs. The aim of the present study was to detect the genetic variants significantly associated with body traits in crossbred pigs using the Illumina Porcine SNP50 BeadChip and imputed whole‐genome sequence data. A set of ...

Subject:
Loa; animal genetics; genes; mutation; phenotype; progeny
Abstract:
... Several genetic variants have been shown to affect the mean number of offspring in different sheep breeds. Here, we analyzed samples from Icelandic sheep with the aim of identifying the genetic cause of the Icelandic Loa phenotype using three previously identified prolificacy genes as candidates. We demonstrate that a 4‐bp frameshift deletion positioned in the mature region of the GDF9 protein in ...

DEAD-box RNA helicases; Tan sheep; Y chromosome; alleles; animal genetics; gene expression; human genetics; nucleotide sequences; quantitative polymerase chain reaction; testes; testicular development
Abstract:
... Variations in the Y‐chromosome are usually correlated with male‐specific traits. However, this condition has been described only sporadically, even in human genetics. The present study was conducted to clone the full‐length gene sequence of ovine DEAD‐box helicase 3, Y‐linked (DDX3Y), and investigate the effect of the expression and variation of DDX3Y on the reproductive traits of Hu sheep. Conseq ...

animal genetics; genes; genome-wide association study; lactation; models; phenotype; quantitative polymerase chain reaction; sheep; swine
Abstract:
... The multiple teats trait is common in many species of mammals and is considered related to lactation ability in swine. However, in Hu sheep, related gene research is still relatively limited. In this study, a genome‐wide association study was used to identify genetic markers and genes related to the number of teats in the Hu sheep population, a native Chinese sheep breed. A single marker method an ...
