Morphologically sex that is undifferentiated are characterized in a number of organisms, including the medaka seafood (28–30) and also papaya (31). That Y chromosome associated with medaka is totally homologous towards their counterpart apart off for a 250-kb chromosomal that is male-specific containing that the male-determining DMY/DMRT1Yb gene (28–30).
That the male-specific area associated with the papaya Y chromosome makes up ?10per cent regarding the chromosome (31). All cases lead united states inside guess that their region that is differentiated that Z as well as W chromosome out of P. Molurus, and potentially have sex-determining gene(s), is simply too limited become detected through banding practices to comparative SEAFOOD mapping. Inside E. Quadrivirgata to T. Flavoviridis, that the brief supply regarding the W chromosome is actually thoroughly degenerated, plus very little homology between your Z plus W chromosomes continues to be with their exception of the telomeric regions, where in fact the BamHI duplicate element was localized.
