These species thus provide a rich resource to study sex chromosome biology in a comparative manner and show that similar selective forces have shaped the unique evolution of sex chromosomes in diverse fly taxa. Additionally, we discuss implications for haploinsufficiency of critical pseudoautosomal region sex chromosome genes, driven by sex chromosome loss, in promoting hematological malignancies.

However, recombination suppression has not spread across the added region, suggesting that linkage between the sexually antagonistic locus and the sex determining locus may not explain the fusion event The degeneration of the sex -determining region due to the accumulation of deleterious mutations is expected to be slower in haploid organisms because of the absence of masking.

Theoretical model of sex chromosome differentiation.

Current Biology. The Nucleus Explanation: The homologous chromosomes are pair of maternal and paternal chromosomes. There is a gene in the Y-chromosome that has regulatory sequences that control genes that code for maleness.

If it occurs after sex chromosomes are established, dosage should stay consistent between the sex chromosomes and autosomes, with minimal impact on sex differentiation.

Gametocidal chromosomes enhancing chromosome aberration in common wheat induced by 5-azacytidine. Genetic recombination is targeted towards gene promoter regions in dogs. Chromosomes and their meiotic behavior in two families of the primitive infraorder Dipsocoromorpha Heteroptera.

Notably, the association between phenotypic sex and linkage group 2 LG2 has been found to be perfect in a northern Swedish population, but weak and variable among families in a southern one.
