Study Notes
Introduction to Genetics
- Every organism inherits traits from its parents, including plants, animals, microbes, and humans.
- Genetics provides insights into what makes organisms unique, exploring inheritance, variation, and gene regulation.
Domestication & Selective Breeding
- Domestication involves selective breeding of animals, transforming species such as wolves into dogs and wild horses into domesticated breeds.
- Historical domestication examples include camels, oxen, and cattle.
Historical Background of Genetics
- The origins of genetics trace back to hybridization theories discussed in the mid-19th century.
- The term "genetics" was coined in 1906 by William Bateson at the 3rd International Conference on Plant Hybridization, emphasizing the study of heredity and variation.
Key Figures in Genetics
- Gregor Mendel laid the foundation for genetic theory through his work on plant hybridization published in 1866.
- Mendel's discoveries were later independently rediscovered by scientists such as Hugo de Vries, Carl Correns, and Erich von Tschermak.
- William Bateson further promoted Mendel's principles and the concept of genetics.
Concepts of Heredity
- Heredity, or biological inheritance, refers to the transmission of traits from parents to offspring.
- The gene, a DNA region encoding specific traits, serves as a basic unit of heredity and genetic variation.
Important Breakthroughs in Genetics
- Development of the Cell Theory by Schwann, Schleiden, and Virchow shaped biological understanding.
- The scientific community moved away from the notion of spontaneous generation after rigorous investigations.
Ancient Contributions
- Early ideas about heredity were posited by the Hippocratic School of Medicine and Aristotle, who theorized the presence of "humors" as hereditary carriers.
