Population evolution analysis
Whole genome resequencing
By sequencing the genomes of different individuals or groups of species with reference genome sequences and analyzing the genome differences of individuals or groups, we can quickly evaluate and screen resources, obtain a large number of genetic variation, and realize genetic population structure, evolutionary analysis, location of important candidate genes, screening and development of functional gene molecular markers. Whole genome resequencing is an effective method for animal and plant breeding and population evolution.
Carry out whole genome re sequencing or simplified genome sequencing for different subgroups in the natural population of species, obtain a large amount of high-accuracy variation information such as SNP and indel through comparison with the reference genome or cluster analysis, study the genetic structure, genetic diversity analysis and selection analysis of the population, and then reveal the evolutionary mechanism, population evolutionary dynamics and process of the species from the molecular level A series of problems such as gene exchange and environmental adaptability.
