The recent characterization of MSCI in birds [ 22 yy sex chromosomes in Independence indicates that this phenomenon, previously only known from XY species [ 18 ], is likely to be associated with heteromorphic sex chromosomes in general. Kondrashov, F. Ann N Y Acad Sci. Female-biased gene expression in the malaria mosquito Anopheles gambiae.
A few species of fish, reptiles, and insects reproduce by parthenogenesis and are female altogether. Sex-biased evolutionary forces shape genomic patterns of human diversity.

Comparison of the chicken and turkey genomes reveals a higher rate of nucleotide divergenceon microchromosomes than macrochromosomes. Evolution of Sex Determining Mechanisms. Nature Reviews Genetics 2 , Second, if there is co-evolution between sex-ratio distorters and MSCI, divergence between species at loci controlling MSCI could give rise to sterility-causing incompatibilities [ 27 , 59 , 60 ].
Consider sexual antagonism, wherein an allele increases fitness in one sex but reduces it in the other.
