Objective To determine the genetic variation and genetic relationship between the wild mouse captured from Lankao county,Henan province,and four common strains of laboratory mice(B6,BALB/c,DDK,PWK),and to construct a wild-origin inbred line mouse.Methods Totally 25 pairs primers were used to identify DNA polymorphisms that distinguish the five strains of mice by amplified fragment length polymorphism(AFLP).Results AFLP primer combinations detected a total of 2035 amplification bands.There were 507 polymorph...
