It is not the case that the "more" chance there is, the more intense the -game. This is to conceptualize both games and chance in terms of a sort of "freedom" ofcombination, an immanent drifting, a constant dissociation of orders and sequences, an unbridled improvisation of desire - a kind of daimon who blows in all directions, ng a little uncertainty, an additional incidence into the world's orderly economy.

Further bioinformatical analysis indicated that the three Y-box genes of lamprey, i.e., Lyb1, Lyb2, and Lyb3, encoded 331, 181, and 171 amino acids, respectively. The three amino acid sequences were homologically aligned with those from Ciona intestinalis, Danio rerio, Oryzias latipes, Takifugu rubripes, and Mus musculus by DNAMAN software.
