E. Gootwine et al., THE DUPLICATED GENE COPY OF THE OVINE GROWTH-HORMONE GENE CONTAINS A PVUII POLYMORPHISM IN THE 2ND INTRON, Animal genetics, 24(4), 1993, pp. 319-321
PvuII restriction fragment length polymorphism (RFLP) was found at the
growth hormone locus in sheep carrying the GH2 allele where the gene
is duplicated. By restriction analysis and using the polymerase chain
reaction we demonstrated that this RFLP is due to a mutation at the Pv
uII site located in the second intron of the 3' copy of the GH2 allele
.
