Location of Peg3 on the proximal portion of mouse chromosome 7. (A) The segregation patterns of Peg3 and the neighboring gene markers in 160 interspecific backcross animals. Each column represents a type of parental or recombinant chromosome, with solid boxes representing 129/Sv alleles and open boxes denoting M. spretus alleles for a given gene. The number of animals inheriting a particular type of chromosome is listed at the bottom of each column. Gene markers listed together in the same row showed identical segregation pattern in this interspecific backcross system. Gene markers in parentheses represent human genes. (B) The partial genetic map of the proximal chromosome 7 showing the location of Peg3 relative to other gene markers. The genetic distances (in centimorgans) between markers are listed at left. Peg3cosegregates with Zfp132.
