Comparison of the sequences among these strains and the sequences reported previously for the two other strains, F1(Gunpo X Shugyoku) and Daizo, indicates that polymorphisms are present in the 5'-flanking and intron regions and that each region has at least two sequence variants independent of each other. These results suggest that crossing over between the heteromorphic H-chain alleles has occurred during the breeding of these strains."}
