First, there is a reduced sequencing coverage of nearly half of the Muller element F homologs in male cockroach, consistent with a haploid dose of the X chromosome in males (Fig. 2). Second, there is a decreased heterozygosity of element F homologs in male cockroach, including those with reduced male sequencing coverage (Fig. 3). We therefore hypothesize that element F is an ancient X chromosome that was present in the most recent common ancestor (MRCA) of flies and cockroaches, and it has been conserved as an X chromosome in the German cockroach and many fly species.”"]]
