The average [r.sup.2] for SNPs separated by intervals 0 to 25 kb, 25 to 50 kb, 50 to 100 kb, 100 to 500 kb, 0.5 to 1 Mb, 1 to 5 Mb and 5 to 10 Mb in each autosomal chromosome are presented in Table 3.
The most appropriate SDs were found by BLASTing the sequence of chromosome 21 against the human genome based on the following criteria: (a) the segments of chromosome 21 and reference chromosomes were amplified simultaneously with a single primer set, and the amplicons were different in sizes due to size variation and (b) sex chromosomes and some autosomal chromosomes such as 13 and 18 were not selected as reference chromosomes since they have a higher chance of numerical abnormalities than other autosomes.
Although the TMRCAs of the mtDNA and Y chromosomes are around the same date as the earliest fossils with modern morphology, the much higher levels of retained diversity in the autosomal chromosomes are only compatible with an earlier bottleneck, not with two people.
Neo-sex and multiple sex-chromosome systems have been reported in a wide array of animal groups other than the Orthoptera and details of their formation strongly depend on the nature of the involved sex and autosomal chromosomes. For example, in Acridoidea, with basic telocentric karyotypes (see below), centric fusions produce neo-XY/neo-XX systems (Fig.
Using a new kind of SNP microarray chip, the investigators assessed a set of 104,268 SNPs that were localized to the autosomal chromosomes. In each of the sample pools, alleles with frequencies of 2% or higher could be identified, allowing the study of many more SNP markers for more unrelated individuals than were previously available.
