As in many diploid organisms with genetic sex determination, haploid-dominant have also evolved chromosomes or extensive genomic regions that lack recombination. An understanding of chromosome evolution should explain the causes and consequences such both diploids haploids. However, haploids been little studied, even though differences from carry implications concerning suppressed recombination organisms, make predictions about genome sex-linked can now be tested by approaches using sequences. I review these ideas, current empirical evidence them, more detail than recent reviews focusing on progress mechanisms involved determination. discuss one specific prediction, degeneration minor haploids, is not upheld. suggest this prediction does take account all processes leading to gene loss profound may evolve if genes become duplicated autosomes, a process appears occur diploids. emphasize types data are needed testing several ideas described.
