The evolution of sex chromosomes: similarities and differences
... The evolution of identifiable heteromorphic sex chromosomes is initiated by the spread of a sex-determining gene (SDG). This occurs when a new mutation at a locus leads all its carriers to become the same (subsequently heterogametic) sex, with the chromosome carrying this mutation becoming the Y/W c ...
