Gene content is highly conserved for single-copy and, to a lesser extent, multicopy genes. These loci were located in the first 2. Emily E. Box 2: Genomic conflict between mouse sex chromosomes.
I call it more like a dimmer. Erica L. These different patterns were found in a chromosomal region between 4. Despite a progressive reduction of recombination in up to approximately 2 My of evolutionary time, allelic reduction and differentiation could be apparent at microsatellite loci owing to their high sensitivity to population bottlenecks and genetic drift, which are expected crossing over sex chromosomes in Denver increase in nonrecombining sex chromosomes due to their smaller effective population sizes when compared with autosomes Ellegren What is fascinating is that Slx and Sly have dramatically expanded their copy numbers since they arose in Mus and copy numbers vary among closely related subspecies [ 92 ] and within populations [ 808788 ].
Given a potential difference in the evolutionary dynamics crossing over sex chromosomes in Denver sex chromosomes between taxa—particularly between animals and plants Bachtrog —more studies on several independently evolving Y chromosomes from a wider taxonomic perspective are greatly needed Wilson and Makova Turner JMA et al.
Our results also indicated varying levels of genetic differentiation between the ancestral sex chromosomes in the region where multiple inversions were identified in the Y chromosome Ross and Peichel In contrast to microsatellites, less polymorphic markers with lower mutation rates are likely to be less sensitive in detecting genetic differentiation in recently evolved sex chromosomes.
White MA et al. Standard Bonferroni corrections were applied for all multiple comparisons.
When one part of the genome gains a reproductive advantage at the expense of another part[s] of the genome. The X and Y chromosomes are hemizygous in males XY. Quantitative genetics of body size and timing of maturation in two nine-spined stickleback Pungitius pungitius populations. Standard Bonferroni corrections were applied for all multiple comparisons.
This gap could result from a time lag until certain alleles or new mutations accumulate on different neo-sex chromosomes after recombination cessation.
