Fig. 1From: The evolutionary process of mammalian sex determination genes focusing on marsupial SRYsComparison of HMG domain in SRY and SOX genes. The amino acid sequence alignment of HMG domain is shown. The gray box represents the position of the HMG domain. Eutherian-specific substitutions are indicated in blue, and marsupial-specific substitutions are indicated in green. The substitutions common to Theria are indicated in yellow.
