Unit 3031: Foundations and Advances in Genetics

1. Introduction to Genetics

• Definition and scope of genetics
• Key concepts:
  • Genes and alleles
  • Chromosomes and karyotypes
  • DNA structure and function
• Role of genetics in heredity and variation

2. Mendelian Genetics

• Gregor Mendel's experiments and significance
• Mendel's Laws:
  • Law of Segregation
  • Law of Independent Assortment
• Use of Punnett squares:
  • Monohybrid crosses
  • Dihybrid crosses
• Examples and practice problems

3. Non-Mendelian Inheritance

• Incomplete dominance
• Codominance
• Multiple alleles (e.g., blood groups)
• Polygenic traits (e.g., skin color, height)
• Sex-linked traits and inheritance patterns

4. Chromosomal Abnormalities

• Overview of chromosome number and structure abnormalities
• Common disorders:
  • Down syndrome (Trisomy 21)
  • Turner syndrome (Monosomy X)
  • Klinefelter syndrome (XXY)
• Other chromosomal disorders and their symptoms
• Diagnostic techniques (e.g., karyotyping, FISH)

5. Genetic Mutations

• Types of mutations:
  • Point mutations (substitutions)
  • Insertions and deletions (frameshift mutations)
  • Chromosomal rearrangements (translocations, inversions)
• Impact on gene expression and protein function
• Examples of mutation-driven diseases

6. Human Genome Project

• Goals and timeline of the project
• Methods used for genome mapping and sequencing
• Key achievements and discoveries
• Implications for personalized medicine and genetic research

7. Genetic Engineering and Biotechnology

• Recombinant DNA technology
• Gene editing techniques (e.g., CRISPR-Cas9)
• Cloning and its applications
• Genetically modified organisms (GMOs) in agriculture and medicine
• Benefits and risks of genetic engineering

8. Ethics and Genetics

• Ethical issues in genetic testing and gene therapy
• Designer babies and genetic enhancement debates
• Privacy concerns and data protection in genetics
• Importance of informed consent in genetic research
• Regulatory frameworks and societal impact
