Genomic analysis of sex chromosome evolution theory in Stafford

Open in a separate window. Never settling down: frequent changes in sex chromosomes. Scientific Data

Although this is the most straight-forward transition theoretically, it is also one of the most difficult to demonstrate, as it requires knowledge of the sex-determining gene in multiple species. Nanda, I. Select Format Select format. Westergaard M.

Methods 9— For this analysis, we only considered autosomal biallelic sites that had coverage in all individuals. Smaller population size and the resulting lower nucleotide diversity on the Z chromosome may therefore partly explain inflated F ST estimates on the Z chromosome.

  • Sex chromosomes have evolved multiple times in many taxa. The recent explosion in the availability of whole genome sequences from a variety of organisms. Sex chromosomes are disproportionately involved in reproductive isolation of the sex chromosomes during speciation (dominance theory) (Turelli & Orr, ). Faster male evolution targets genes with male‐biased effects, which may Genotypes were called using the genome analysis tool kit (GATK).

  • Comparative genomic studies have shown that quite distant species may share fundamental properties of sex chromosome evolution, while very similar species can evolve unique sex chromosome systems. Furthermore, within-species genomic analyses can illuminate chromosome-wide sequence and expression by: 4/21/ · Genomic analysis of many nonmodel species has uncovered an incredible diversity of sex chromosome systems, making it possible to empirically test the rich body of evolutionary theory that describes each stage of sex chromosome evolution. Classic theory predicts that sex chromosomes originate from a pair of homologous autosomes and recombination between them is suppressed via Cited by:
