Mapping and validation of sex-linked SNP markers in the swimming crab Portunus trituberculatus

Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.

Single nucleotide polymorphism SNP19140160 A > C is a potential breeding locus for fast-growth largemouth bass (Micropterus salmoides)

“…SNPs are variants with low redundancy and high coverage in the genome, and they can be used to facilitate high-throughput genotyping [34]. They have been widely used to construct high-density genetic linkage maps and discover QTL and economic trait-related genes [35][36][37]. Li et al (2017) used RNA-seq data to mine for fast-growth-related SNPs in largemouth bass.…”

A refined roadmap to decapod sexual manipulation

“…In crabs, all‐male or all‐female populations are preferred over mixed populations 33–35 . The reason is that although males grow faster than females, prices of females with mature ovaries are significantly higher than males of the same size 33,36 . All these examples clearly indicate how sexual manipulation in decapods is necessary to support higher yield, higher profit or enhanced aquaculture productivity.…”

“…[33][34][35] The reason is that although males grow faster than females, prices of females with mature ovaries are significantly higher than males of the same size. 33,36 All these examples clearly indicate how sexual manipulation in decapods is necessary to support higher yield, higher profit or enhanced aquaculture productivity. In addition to aquaculture applications, monosex populations of decapods can not only manage the spread of carriers of human pathogens; since monosex populations cannot breed, they can be safely deployed as a biocontrol agent in Western African countries to combat schistosomiasis infestations, and also to reduce invasion risk of cultured invasive alien species.…”
