Reduced levels of microsatellite variability on the neo-Y chromosome of Drosophila miranda

Abstract: Variability of the neo-Y chromosome of D. miranda is substantially reduced below expectations at mutation-drift equilibrium. Such a reduction is predicted by theories of the degeneration of the Y chromosome. Another possibility is that there is little or no mutation at microsatellite loci on a non-recombining chromosome such as the neo-Y, but this seems inconsistent with other data.

“…Genomic regions with reduced rates of crossing-over, and likely overall recombination, show reduced neutral y in many different eukaryotic genomes (Aguadé et al, 1989;Stephan andLangley, 1989, 1998;Berry et al, 1991;Begun and Aquadro, 1992;Martin-Campos et al, 1992;Langley et al, 1993;Aguadé and Langley, 1994;Stephan, 1994;Aquadro et al, 1994;Moriyama and Powell, 1996;Nachman, 1997;Dvorak et al, 1998;Kraft et al, 1998;Nachman et al, 1998;Zurovcova and Eanes, 1999;Bachtrog and Charlesworth, 2000;Przeworski et al, 2000;Andolfatto and Przeworski, 2001;Baudry et al, 2001;Jensen et al, 2002;Wang et al, 2002;Cutter and Payseur, 2003). Mitochondrial genomes, which lack recombination in many species, also show reduced level of polymorphisms (Weinreich and Rand, 2000).…”

“…First, the evolutionary history of the Y chromosome would be shaped by selective sweeps; the accretion of each new Y-linked gene is accompanied by fixation of a single Y chromosome (and there may be additional sweeps caused by the fine-tuning of the genes to male fitness). These selective sweeps span the entire chromosome (there is no recombination in the Y) and may help to explain the low nucleotide diversity of the Drosophila Y chromosome (33,34). Second, the genic content of the Y chromosome would be fluid and may differ among Drosophilid species.…”

“…For example, it has been postulated recently, that the human Y chromosome is the result of at least four inversions that prevented recombination over large regions of the X and Y (Lahn & Page, 1999). The Y chromosome of the plant Silene latifolia, and the neo-Y chromosome of Drosophila miranda, which results from a fusion between a chromosome arm and the old Y chromosome, are much more recent than this (Filatov et al, 1999 ;Bachtrog & Charlesworth, 2000 ;Yi & Charlesworth, 2000). The same principles that apply to a primeval non-recombining Y chromosome also apply to a neo-Y chromosome of Drosophila.…”
