“…Traditional genetic breeding programs mainly rely on phenotypic trait selection, which has a long breeding cycle and low selection efficiency ( Zenger et al, 2017 ). Fast and effective breeding methods, such as marker-assisted selection (MAS), can use genetic information to select important traits, which provides convenience for genetic selection ( Raina et al, 2020 ).…”

Red swamp crayfish (Procambarus clarkii) is a commercially important species in global aquaculture and most successfully invasive freshwater shrimp in China. In order to determine the genetic basis of growth- and sex-related traits, a high-density genetic linkage map was constructed using 2b-RAD sequencing technology in a full-sib family. The consensus map contains 4,878 SNP markers assigned to 94 linkage groups (LGs) and spanned 6,157.737 cM with an average marker interval of 1.26 cM and 96.93% genome coverage. The quantitative trait locus (QTL) mapping for growth and sex traits was performed for the first time. QTL mapping uncovers 28 QTLs for growth-related traits in nine LGs, explaining 7.9–14.4% of the phenotypic variation, and identifies some potential candidate growth-related genes such as mih, lamr, golgb1, nurf301, and tbcd1 within the QTL intervals. A single major locus for sex determination was revealed in LG20 that explains 59.3–63.7% of the phenotypic variations. Some candidate sex-related genes, such as vps4bl, ssrf, and acot1, were identified in the QTL intervals and found to be differentially expressed in the muscle tissues between the females and the males. Furthermore, the identified SNPs were revealed to be female heterozygotes, suggesting that red swamp crayfish might have the female heterogametic ZZ/ZW sex determination system. The present study provides a valuable resource for marker-assisted selection and genetic improvement and for further genetic and genomic research in red swamp crayfish.

“…Efficient breeding and selection strategies are essential through repeatability, heritability, and correlation among various traits (Tesema et al, 2020). According to previous investigations, genetic improvement of livestock has been achieved using marker‐assisted selection (MAS) (Raina et al, 2020), which is used for the indirect selection of superior breeding animals. MAS is beneficial when the traits are difficult and expensive to measure, expressing low heritability and recessive traits.…”

Genetic polymorphisms within the ETAA1 gene associated with growth traits in Chinese sheep breeds

et al. 2022

Summary Ewing tumor‐associated antigen 1 (ETAA1) is an important candidate gene for fat deposition in sheep. This study aimed to investigate the indel variations in the ETAA1 gene and their associations with growth traits in the 1619 sheep. The polymorphism information content of this indel ranged from 0.308 to 0.375, with medium genetic diversity (0.25 ≤ polymorphism information content ≤ 0.5). The correlation analysis showed that an 8‐bp insertion within the ETAA1 gene was significantly associated with growth traits in Luxi Blackhead sheep (LXBH), Lanzhou fat‐tailed sheep, Hu sheep, Tong sheep, and Tan sheep (p < 0.05). Furthermore, the ETAA1 gene was significantly associated with several growth traits (p < 0.01), such as chest width and paunch girth of LXBH, Tong, and Tan rams. It was significantly related to the body morphometric traits of LXBH, Lanzhou fat‐tailed sheep, Hu, Tong, and Tan ewes. In conclusion, the detected 8‐bp indel within the ETAA1 gene was confirmed in sheep, significantly affecting the growth traits, and might be a potential DNA marker for the selection of high‐quality individuals in marker‐assisted selection for sheep breeding.

“…Identification of gene alleles associated with economically important traits allowed using them for marker-assisted selection (Pighetti, Elliott, 2011;Abd El-Hack et al, 2018). Marker-assisted selection is particularly important for traits that become evident with age or only in animals of the same sex, such as productivity or fertility (Zinovieva, 2016;Raina et al, 2020).…”

Comparative analysis of allele frequencies for DNA polymorphisms associated with disease and economically important traits in the genomes of Russian and foreign cattle breeds

et al. 2022

The genetic makeup of a breed including its genetic differences from other breeds determines its appearance and characteristics, including economically important traits and resistance to pathologies. To date, many loci controlling significant phenotypes have been identified, which is successfully used in the world practice of marker-assisted selection to improve breed properties. The aim of this study was a comparative analysis of frequencies for known causative nucleotide substitutions, insertions and deletions associated with disease and economically important traits in Russian and foreign cattle breeds. As a result, we identified frequencies of these DNA polymorphisms in the populations of Russian cattle breeds, compared them with those of foreign populations of the same breed, as well as other foreign breeds. Our results indicate similarities in frequencies for most of such alleles within breeds (populations of Russian and foreign breeding), as well as the relationship between the causative allele prevalence and the presence of phenotypic traits under the effect. We also found an excess of some undesirable alleles in the Russian cattle populations, which should be paid attention to when designing breeding programs. We found that the alleles increasing fertility in the Hereford breed have a higher frequency in the Russian Hereford population compared to the foreign counterpart. Interestingly, unlike for the European breeds, for Asian Turano-Mongolian Wagyu and Yakut cattle, there was a less clear link between phenotypic traits and frequencies of known causative alleles. Our work points to specific genetic variants that could be used to improve and/or maintain the performance of certain cattle breeds bred in the Russian Federation.
