    Study Notes

    Understanding Genetic Information and Its Implications

    • Genetic information is redundant and genes and proteins are meta-stable.
    • Genomic comparisons between species can answer questions about evolution and the importance of non-coding regions and genes.
    • Types of polymorphisms include Single Nucleotide Polymorphism (SNP) and Copy Number Variation (CNV).
    • The International HapMap Project aimed to define patterns of genetic variation across human genomes and identify patterns of genetic variation across different populations.
    • Haplogroups can be used to trace human migration patterns through observing branching points in an ancestral map.
    • The 1000 Genomes Project aims to describe human genetic diversity in over 1000 individuals from multiple populations.
    • The UK NHS-based 100,000 Genomes Project focuses on rare diseases, common cancers, and infectious diseases.
    • Personal genomics involves deducing a person's entire genetic code and can be achieved through SNP analysis or genome sequencing.
    • Genetic variation is responsible for adaptive changes and can lead to both advantageous and maladaptive changes, possibly representing diseases.
    • Genome-wide association studies (GWAS) aim to find connections between heritable phenotypes and whole-genome genotypes and can be used to predict phenotypes from genotypes.
    • GWAS involves scanning markers across genomes to find genetic variations associated with specific diseases, which can lead to the development of better disease detection, treatment, and prevention strategies.
    • The use of genetic information regarding common diseases can lead to personalized medicine, with individualized approaches to patients and improved health outcomes.
