What are Genotypes? Coalescent Theory: An Introduction. First, there are more species with Y-A fusions species than with X-A fusions 27 species. To assess the relative rates of the establishment of fusions, we mapped fusion status onto the phylogenetic trees of fishes Fig 2 and squamate reptiles Fig 3.

We then ask how these neutral results are altered by the three main evolutionary forces thought to impact the rate of fusions: direct selection, meiotic drive, and sexually antagonistic selection. We find that Y-autosome fusions become established at a much higher rate than any of the other three types of sex chromosome-autosome fusions.

  • An autosome is one of the 22 numbered pairs of chromosomes that most of us carry in almost all of the cells of our body. We actually have a total of 23 pairs of chromosomes in these cells, for a total of 46 chromosomes, but two of those are referred to by letter rather than by number and are called sex chromosomes rather than autosomes, since they--that is the X and Y chromosome--help. Autosome, any of the numbered or nonsex chromosomes of an organism. Humans have 22 sets of autosomes; they are referred to numerically (e.g., chromosome 1, chromosome 2) according to a traditional sort order based on size, shape, and other properties. Autosomes differ from sex chromosomes, which make up the 23rd pair of chromosomes in all normal human cells and come in .
