Key Concepts in Genetics
- Genetics Definition: Derived from Greek "gen," meaning to grow or become.
- Founding Figures: Gregor Mendel established the foundational principles of heredity through experiments with garden peas.
Gene Characteristics
- Genes are inherited across generations.
- Provide information on traits.
Theories of Inheritance
- Pangenesis (Aristotle): Semen formed throughout the body reflecting characteristics of various parts.
- Lamarck's Theory: Modifications acquired through use/disuse can be inherited.
- Weismann's Germplasm Theory: Challenges Pangenesis; proposes sex cells (germplasm) perpetuate across generations.
Key Historical Contributors
- Joseph Gottlieb Kolreuter: Noted that hybrids displayed diversity in offspring.
- Gregor Mendel: Known as the Father of Genetics for his work on inheritance patterns.
Mendel's Work Relevance
- Mendel's work largely unrecognized for 40 years due to mathematician-biologist divide and issues with research species.
Meiosis Overview
- Occurs during gametogenesis in spermatogenesis and oogenesis.
- Comprises two division phases: Meiosis I and II.
Concept of Gene Segregation
- Mendel's Laws:
- Law of Independent Segregation: Alleles separate wholly during meiosis.
- Law of Independent Assortment: Alleles from different gene pairs assort independently.
Types of Genetic Crosses
- Monohybrid Cross: Crossing between homozygous individuals differing at a single gene locus.
- Recessive Epistasis: One gene masks another's effect when homozygous recessive.
- Complementary Genes: Recessive alleles of either gene may mask dominant effects of the other.
Phenotypes from Gene Interaction
- New phenotypes arise from interactions among dominant and recessive alleles across different gene pairs.
