Unit 3019: Comprehensive Genetics

1. Overview of Genetics

• Introduction to genetics
• Structure and function of DNA
• Genes and chromosomes
• Principles of heredity
  • Alleles
  • Genotype vs phenotype
  • Homozygous and heterozygous

2. Mendelian Genetics

• Gregor Mendel's experiments
  • Pea plant traits
  • Law of segregation
  • Law of independent assortment
• Dominant and recessive traits
• Punnett squares
  • Monohybrid crosses
  • Dihybrid crosses
• Genetic ratios and probabilities

3. Non-Mendelian Inheritance

• Incomplete dominance
• Codominance
• Multiple alleles
  • Example: ABO blood groups
• Polygenic inheritance
  • Examples and traits
• Sex-linked traits
  • X-linked recessive and dominant
  • Examples: Hemophilia, color blindness

4. Genetic Mutations

• Definition and types
  • Point mutations
  • Insertions and deletions
  • Chromosomal mutations
• Causes of mutations
  • Spontaneous
  • Induced (mutagens, radiation)
• Effects of mutations on organisms
  • Beneficial, neutral, harmful

5. Genetic Disorders

• Chromosomal abnormalities
  • Down syndrome, Turner syndrome, Klinefelter syndrome
• Single gene disorders
  • Cystic fibrosis, sickle cell anemia, Huntington's disease
• Multifactorial disorders
  • Heart disease, diabetes, some cancers

6. Genetic Engineering

• Principles of genetic engineering
• Gene editing techniques
  • CRISPR-Cas9 mechanism
• Genetically Modified Organisms (GMOs)
  • Agricultural and medical applications
• Gene therapy
  • Approaches and challenges

7. Population Genetics

• Genetic variation in populations
• Gene pool and allele frequency
• Evolutionary forces
  • Genetic drift
  • Gene flow
  • Natural selection
• Hardy-Weinberg equilibrium

8. Genomics and Personalized Medicine

• The field of genomics
• The Human Genome Project overview
• Advances in sequencing technologies
• Personalized medicine
  • Pharmacogenomics
  • Tailored treatments based on genetic profiles

9. Ethical and Social Implications of Genetics

• Ethical dilemmas in genetic research
• Genetic testing and privacy concerns
