To address this question, it will be required to determine whether H3K9me3 enrichment on gene-rich portions of chromosome 14 and chromosome 5 is established in spermatocytes or in spermatids. Insect Biochem. Effectiveness of phylogenomic data and coalescent species tree methods for resolving difficult nodes in the phylogeny of advanced snakes Serpentes: Caenophidia Mol.
Adams R. Origin of amniote sex chromosomes: An ancestral super-sex chromosome, or common requirements?
Papaya shared a common ancestor with Arabidopsis approximately 72 million years ago. Reproduction Cambridge, England. Thus, the presence of microsatellites motifs in the W chromosomes of phylogenetic divergent groups led us to suppose that these sequences might have some role in the process of the sex chromosome differentiation.
Similar proportions of non-reactivated genes are found for all chromosomes. Oliveira et al.
