Study Notes
Introduction to Plant Genetics
- PLNT3333 course details: lectures on Mondays, lab on Wednesdays, taught by Dr. Sovetgul Asekova
- Dr. Sovetgul Asekova's background: MSc and PhD in plant genetics, post-doc in Korea, expert in GWAS, GBS, and NGS
What is Genetics?
- Genetics is the study of genes and heredity
- Involves the study of variation and its causes
- Definitions:
- Gene: unit of heredity transmitted from one generation to the next
- Heredity: process that brings about similarity between parents and offspring
- Variation: differences between individuals of a family or species
Types of Variation
- Genetic variation: differences due to genetic differences
- Environmental variation: differences due to environmental factors
- Interaction between genetic and environmental factors (G x E interaction)
Plant Development and Cell Division
- Increase in plant size occurs after cell division
- Cell division occurs through mitosis
- Cell growth and development involve precise cellular reproductive mechanisms
Introduction to Gregor Mendel
- Gregor Mendel: monk and botanist who conducted experiments with pea plants
- Discovered the fundamental laws of inheritance
- Conducted experiments in the Augustinian Abbey in Brno, Czech Republic
