Methods Fifty pairs of fresh colorectal cancer and homologous normal tissues were genotyped with Identifiler Kit and the mutations generated in cancer tissues were determined. The mutation rates, the numbers of locus matched without identical allele (A0), 1 identical allele (A1), or 2 identical alleles (A2) and the number of total identical alleles IA(subscript n were calculated. Frequency distributions of A0, A1, A2 and IA were compared among CR-N group, unrelated individual pairs and full sibling pairs. Discrimination functions were established for individual identification from tumor tissues with discriminatory analysis.

The differentiation coefficient is 0.07 between three inbreed families respectively. The highest level of genetic homozygosity is in families Ⅱ at 18, but genetic variation is a little difference between inbreeding pig and mice. However, this study revealed the pattern of genetic variation at microsatellite loci in the 3 inbred families of WZSP with one of the most important findings to be the high level of unexpected heterozygosity at some loci, e.g. Sw874 and Sw936 that could be part of the unique genetics of three families. A hypothesis is that certain functional genes linked with such microsatellite loci may be involved in the maintenance of viability of these inbred families of WZSP remains for further investigation.

随近交代数的推进，每个星座上等位基因数越来越少，基因的纯合度越来越高，但WZSP近交系微卫星等位基因的纯合度有一定的限度，与近交鼠有所不同；在近交系3个家系各个世代中有少数几个基因座，如Sw874和Sw936等一直处于高度杂合状态，这可能与WZSP近交家系的种质特异性有关，推测与这些基因座处于同一连锁群的某些功能基因在维持极高近交水平下WZSP的基本生存能力中起着关键作用。3个近交群体间的分化系数在0.07以上，已各自成为独立家系；3个家系的近交程度不完全一致，基因的纯合度亦不同，Ⅱ系最高、14个微卫星座中7个纯合，其次为Ⅰ系和Ⅲ系。

The ISSR markers were fitted to a 3:1 ratio of simplex and duplex segregation for the parental alleles, as the sweet potato was expected to be autohexaploid. Fourteen and nine quantitative trait loci linked to specific ISSR markers were detected for traits in (NH×TN27) and (TN27×NH), respectively. Twenty-two of these QTL-mapped markers were unique to the specific traits, and two were linked to two traits in each linkage map. These markers appear to be applicable to crop improvement.

Based on this information, offspring from 10 crosses where parents were known were genotyped by the 6 microsatellite loci and used for parentage analysis. The result showed that assignment success of the progeny to their 'true' mother and father was 88% and 78% respectively, which were lower than predicted by the Cervus simulations. This could be explained by the existence of null or mutant alleles and by Taq DNA Polymerase slippage in the microsatellite loci.
