Article Abstract
To study the genetic polymorphism of Penta E locus in four Chinese nationalities using home made reagent kits, DNA samples were obtained from about 400 unrelated peoples of four different Chinese nationalities. As a result, we found 20 alleles in the four nationalities with frequencies ranging from 0.0048 to 0.2396. The genotype frequencies of Penta E locus met Hardy-Weinberg equilibrium. It proved that Penta E locus was a high polymorphic STR genetic marker and was valuable for forensic science.

Heterostyly is a polymorphic floral adaptation controlled by supergenes. The molecular basis of distyly has been investigated in diploid species from several unrelated families, but information is lacking for polyploid systems. Here, we address this knowledge gap in Schizomussaenda henryi, a tetraploid distylous species of Rubiaceae, the family with the greatest number of heterostylous species.

The S-locus supergene controlling heterostyly has multiple angiosperm origins and is characterized by convergent evolution in form and function. The genetic architecture of floral polymorphism has been studied in several unrelated families, but not Rubiaceae, which has the largest number of heterostylous species. We assembled genomes of the long- and short-styled morphs of distylous Mussaenda lancipetala and investigated the structure and evolution of the S-locus in three Mussaenda species to evaluate evidence for convergence in genetic architecture and gene function in unrelated families.

To develop a 9-dye fluorescent autosomal and Y chromosome STR multiplex amplification system and verify its performance. Using the 9-dye fluorescent labeling technology, construct a multiplex amplification system that uses the autosomal and Y chromosome core and preferred loci recommended by GB/T 41009-2021 national standard as candidate loci, then evaluate its accuracy, sensitivity, species specificity, and other system performance index. A 9-dye fluorescent multiplex amplification system containing 70 loci, including Amel, D5S818, D21S11, D7S820, CS1FPO, D2S1338, D19S433, D8S1132, D2S441, VWA, D8S1179, D16S539, D10S1435, PentaD, D3S3045, TPOX, TH01, D22S1045, D18S51, FGA, D19S253, D10S1248, D6S477, D6S1043, D13S317, D12S391, D15S659, PentaE, D1S1656, D3S1358, DYS460, DYS389I, DYS390, DYS533, DYS392, DYS518, DYS557, DYS570, DYS458, DYS437, DYS385, GATA-H4, DYS576, DYS643, DYS508, DYS627, DYS456, DYS391, DYF404S1, DYS438, DYS448, DYF387S1, DYS596, DYS549, DYS399S1, DYS393, DYS635, DYS439, DYS19, DYS444, DYS449, DYS481, DYS527a/b, and DYS447 was successfully constructed.

Article Synopsis
- Vanishing Twin Syndrome (VTS) is when one fetus in a multiple pregnancy disappears, often discovered through ultrasounds, but its genetic causes are not well understood.
- A case study of a 39-year-old woman who conceived twins via IVF showed that one twin's heartbeat stopped at 11 weeks, confirming VTS while the other developed normally.
- Genetic testing revealed that both fetuses were identical twins with a normal genetic make-up, but the vanished twin exhibited a unique genetic pattern, demonstrating the potential for genetic investigation in cases of VTS.
