Abstract

A Japanese prawn 40K liquid phase chip and application thereof belong to the technical field of whole genome gene chip. The chip contains 41340 SNP molecular markers covering the whole genome of Japanese prawn. The physical position of the SNP site is determined by sequence alignment based on the reference genome (GCA_977035675) of Japanese prawn. The specific site information is shown in table 2 of the specification. The present application provides a first SNP liquid phase chip for Japanese prawn, which is suitable for whole genome association analysis, genetic diversity evaluation, genome selection breeding and parent identification of the species. It helps to speed up the genetic breeding process of excellent traits of Japanese prawn, and has important significance for improving the breeding efficiency and promoting the sustainable development of the industry.
