Premise Of The Study: Microsatellite markers were developed for a distylous-homostylous species, (Primulaceae), to investigate the mating patterns and gene flow in the species.
Methods And Results: Using RAD sequencing, 42,777 contigs were generated. A total of 1566 putative simple sequence repeat (SSR) loci were identified by MISA, and 1433 primer sets were designed. After initial screening of 107 SSR loci, 24 loci displayed polymorphism. The number of alleles per locus detected ranged from one to 11 in the sampled populations of . Levels of observed and expected heterozygosity for each locus ranged from 0 to 0.917 and 0 to 0.816, respectively. Fifteen and 13 of these loci could be successfully amplified in the two congeneric species and , respectively.
Conclusions: The SSR markers developed here will be valuable for genetic analysis and elucidation of mating patterns in .

The current review delves into the transformative role of precision medicine in addressing Colorectal Cancer [CRC], a pressing global health challenge. It examines closely signalling pathways, genetic and epigenetic modifications, and microsatellite in-stability. The primary focus is on elucidating biomarkers revolutionizing CRC diagnosis and treatment.

Studies of the genetics of Alzheimer's disease (AD) have largely focused on single nucleotide variants and short insertions/deletions. However, most of the disease heritability has yet to be uncovered, suggesting that there is substantial genetic risk conferred by other forms of genetic variation. There are over one million short tandem repeats (STRs) in the genome, and their link to AD risk has not been assessed.

Centromochlus heckelii has the lowest diploid chromosome number (2n = 46) and the only described heteromorphic sex chromosome system in Auchenipteridae. This study presents a population of C. heckelii from the Central Amazon basin with subtle variations in the karyotype composition and a variant W chromosome with distinct morphology and increased C-positive heterochromatin content.

Identification of chromosomal abnormalities is an important issue in animal breeding and veterinary medicine. Routine cytogenetic diagnosis of domestic animals began in the 1960s with the aim of identifying carriers of centric fusion between chromosome 1 and 29 in cattle. In the 1970s, chromosome banding techniques were introduced, and in the 1980s, the first cytogenomic techniques, based on the development of locus- and chromosome-specific probes, were used.
