Unusual diversity of sex chromosomes in African cichlid fishes. Mechanisms of Recombination Suppression. Mammalian Y chromosomes retain widely expressed dosage-sensitive regulators. Genome analyses substantiate male mutation bias in many species.
Schoumans, J. In all experiments, both genome-derived probes showed preferred accumulation to chromosome regions previously identified as C-bands genomic analyses of sex chromosome evolution in Moncton C 0 t-1 DNA hybridization sites Born and Bertollo, ; Cioffi and Bertollo, ; Cioffi et al.
Co-evolution of genomic structure and selective forces underlying sexual development and reproduction. Sex determination: why so many ways of doing it? Sex portal. Grath S, Parsch J: Rate of amino acid substitution is influenced by the degree and conservation of male-biased transcription over 50 myr of Drosophila evolution.
Ohno S. In addition, it is entirely possible that the extent of sexual conflict differs across populations that experience different behavioral ecologies, leading to variation in the level of sex chromosome differentiation.
Charlesworth D. Search Menu. While the first three are found on the B. Sex-biased gene expression and dosage compensation on the Artemia franciscana Z-chromosome. The evolution of parasitism in Nematoda.
Gamble T. Laser-based flow cytometry consists of applying an electrical charge to droplets containing chromosomes of interest. In some cases, the emergence of a new sex-determining locus leads to a transition between XY and ZW systems, as has occurred in snakes and amphibians.
