Abstract A theoretical population genetic model is developed to explore the consequences of X-Y recombination in the evolution of sex chromosome polymorphism. The model incorporates one sex-determining locus and one locus subject to natural selection. Both loci have two alleles, and the rate of classical meiotic recombination between the loci is r. The alleles at the sex-determining locus specify whether the chromosome is X or Y, and the alleles at the selected locus are arbitrarily labeled A and a. Natural selection is modeled as a process of differential viabilities. The system can be expressed in terms of three recurrence equations, one for the frequency of A on the X-bearing gametes produced by females, one for each of the frequency of A on the X- and Y-bearing gametes produced by males. Several special cases are examined, including X chromosome dominance and symmetric selection. Unusual equilibria are found with the two sexes having very different allele frequencies at the selected locus. A significant finding is that the allowance of recombination results in a much greater opportunity for polymorphism of the Y chromosome. Tighter linkage results in a greater likelihood for equilibria with a large difference between the sex chromosomes in allele frequency.

Historical Accounts

n the 8th century, the first political boundary between Germany (the land of the Franks) and the Slav people – known as Limes Sorabicus – followed the line of the Rivers Elbe and its tributary the Saale. In later centuries this was breached under the influence of an eastwards political expansion of Germany also characterised by developing German colonisation in that same direction (of the so-called Ostsiedlung). The consequence was for German regional communities to take shape to the east of the old Limes Sorabicus. Alongside the emigrants from the west, further participants in the process where autochthonous Slavs and Balts. This mixed origin of the new communities arising is revealed in historical accounts, but also via the results of scientific analyses of various profiles. The genetic research carried out to date supports the above contention, as well as a conclusion that the zone around the old Limes Sorabicus, despite its running through the centre of what is today an ethnically-German area, continues to represent a separation of populations whose ancestors are mainly of distinct origins.

Y Chromosomes

A Y chromosomal repetitive sequence identified two types of Y chromosomes in mice (Mus musculus domesticus) caught near Ste. Anne de Bellevue, Quebec. One type is apparently identical to the Y chromosome found in Maryland, Delaware, and California, whereas the other type is similar, but not identical, to the Y chromosome present in M.m. poschiavinus, an Alpine race of M.m. domesticus. These findings suggest that the domesticus Y chromosome is highly polymorphic and thus useful for elucidating the relationships among American and European house mouse populations.Key words: mouse Y chromosome, polymorphism, Mus musculus domesticus, repetitive sequence, Quebec.
