Peach (Prunus persica (L.) Batsch) is one of the most important model fruits in the Rosaceae family. Native to the west of China, where peach has been domesticated for more than 4,000 years, its cultivation spread from China to Persia, Mediterranean countries and to America. Chinese peach has had a major impact on international peach breeding programs due to its high genetic diversity. In this research, we used 48 highly polymorphic SSRs, distributed over the peach genome, to investigate the difference in genetic diversity, and linkage disequilibrium (LD) among Chinese cultivars, and North American and European cultivars, and the evolution of current peach cultivars.

The discipline studying genetic composition of populations and effects of factors such as GENETIC SELECTION, population size, MUTATION, migration, and GENETIC DRIFT on the frequencies of various GENOTYPES and PHENOTYPES using a variety of GENETIC TECHNIQUES.
Community centers for older adults and providers of resources for the community. In addition to providing services and activities for older adults that reflect the community's diversity, they link participants with resources offered by other agencies.
Nonrandom association of linked genes. This is the tendency of the alleles of two separate but already linked loci to be found together more frequently than would be expected by chance alone.
Human histocompatibility (HLA) surface antigen encoded by the A locus on chromosome 6. Individuals bearing this allele are more susceptible to Hodgkin's disease. HLA-A1 is in linkage disequilibrium with HLA-B8 and HLA-DR3.
Human histocompatibility (HLA) surface antigen encoded by the A locus on chromosome 6. The allele occurs with increased frequency in individuals with idiopathic hemochromatosis. HLA-A3 is in linkage disequilibrium with HLA-B7 and HLA-DR2.
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
