Study Notes
Cytogenetic Techniques
- Examines the genetic components of cells, including chromosomes, genes, and genetic products
- Diagnoses abnormal chromosomal complements, such as Down Syndrome (Trisomy 21) and Klinefelter syndrome
- Prenatal diagnosis using amniotic fluid or placenta
Biochemical Techniques
- Analyzes DNA, RNA, and protein at the cellular or subcellular level
- Determines activities of genes within cells to analyze substrates and products of gene-controlled reactions
Physiological Techniques
- Explores functional properties of organisms in genetic investigations
- Involves studying cell function in microorganisms and humans
Molecular Techniques
- Involves the direct study of DNA using recombinant DNA technology
- Allows for the manipulation and modification of genomes
Genomics
- Applies recombinant DNA, DNA sequencing, and bioinformatics to sequence, assemble, and analyze genomes
- Analyzes the function and structure of genomes
Branches of Genetics
- Human Genetics: studies inheritance in humans
- Medical Genetics: diagnoses and manages hereditary disorders
- Microbial Genetics: studies genotypes and phenotypes of microbial species
- Molecular Genetics: studies structure and function of genes at a molecular level

History of Genetics
- Dates back to classical era with contributors such as Hippocrates, Aristotle, and Epicurus
- Modern biology began with Gregor Johann Mendel's work on pea plants (1866)
Introduction to Cytogenetics
- Study of biologically inherited traits influenced by the environment
Branches of Genetics (continued)
