Genetics
Genetics is the study of heredity and variation, focusing on the role of chromosomes, genes, and alleles. Key processes such as meiosis, genetic variation, and inheritance patterns contribute to the diversity of traits in organisms. DNA technology has emerged as a powerful tool with applications in medicine, agriculture, and forensic science, enabling manipulation and analysis of genetic material.

What we have learnt
- Chromosomes carry genetic information essential for inheritance.
- Meiosis is crucial for genetic variation in offspring.
- Mendel's laws of inheritance laid the foundation for understanding genetic traits.
- Codominance, incomplete dominance, and sex linkage are important inheritance patterns.
- DNA technology allows for the manipulation of genetic material with diverse applications.
Key Concepts
- -- Chromosomes
- Long strands of DNA coiled around proteins that carry genetic information.
- -- Genes
- Specific sequences of DNA that code for proteins or functional RNA molecules.
- -- Alleles
- Different versions of a gene that arise due to mutations.
- -- Meiosis
- A type of cell division that reduces chromosome number by half, producing haploid gametes.
- -- Mendelian Genetics
- The study of how traits are passed from parents to offspring, based on Gregor Mendel's laws.
- -- DNA Technology
- Techniques used to study and manipulate genetic material, including PCR, gel electrophoresis, and genetic engineering.
