population genetic and inhertiance of diseases

• • Study of genetic variation within population including changes in frequency of of genes and allele within population and among populations over time
• • Development of dna analysis and genetic testing led to diagnosis of genetic diseases and probability of any future offspring inheriting these conditions 
• • Data collected provides potential for large scale genomic analysis to assist in generating data about occurrence of specific genetic conditions in population
• • Prediction of genetic susceptibility to a disease has traditionally been based on family background and pedigree analysis. Large scale screening and DNA analysis can have significant impact on individuals through early detection and improved treatment options
