Facts and Observations in Relation to the X
... Due to the meiotic processes and transmission factors where an X remains intact in a male, males have higher rates of mutations (up to 5 times although other studies report 1.7) on the X than do females. This is often interpreted as being consistent with “male-driven evolution”, and the primary expl ...

Genome evolution
Genome evolution is the process by which a genome changes in structure (sequence) or size over time. The study of genome evolution involves multiple fields such as structural analysis of the genome, the study of genomic parasites, gene and ancient genome duplications, polyploidy, and comparative genomics. Genome evolution is a constantly changing and evolving field due to the steadily growing number of sequenced genomes, both prokaryotic and eukaryotic, available to the scientific community and the public at large.
