Lessons in This Term
Mendel's experiments
Mendelian Genetics and Inheritance Patterns: Mendelian genetics refers to the principles of inheritance discovered by Gregor Mendel through his experiments with pea plants, which form the foundation of classical genetics.
Non-Mendelian genetics
Non-Mendelian Inheritance Patterns: Patterns of inheritance that do not follow Mendel's laws of segregation and independent assortment, resulting in different phenotypic ratios and genetic outcomes.
Evolution and gene frequencies
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

DNA Structure and Properties: Deoxyribonucleic acid (DNA) is a double-stranded helical molecule composed of nucleotides, each containing a deoxyribose sugar, phosphate group, and nitrogenous base (adenine, thymine, guanine, or cytosine).
Genes and gene expression
Genome Organization: The complete set of genetic material present in an organism, including both coding and non-coding DNA sequences, organized into chromosomes.
Molecular basis of mutations
Mutation Definition and Types: A mutation is a permanent alteration in the DNA sequence that makes up a gene, ranging from a single base pair change to large chromosomal rearrangements.

DNA Isolation and Analysis Techniques: DNA isolation is the process of extracting DNA from cells or tissues, which is the fundamental first step in gene technology.
Applications of gene technology
Genetically Modified Organisms (GMOs): Organisms whose genetic material has been altered using genetic engineering techniques, resulting in organisms with new traits or characteristics not found in nature.
