Ch. 1 Introduction to Genetics Flashcards
What are 3 subdivisions of the study of genetics
- Transmission (think of mendels Work genetic traits passed from generation to generation)
- Molecular (cells functions)
- Population ( differences in populations)
What are the 7 genetic model organisms
Fruit fly, arabadopsis thaliana, (mouse) mus musculus, sea elegins, yeast, zebra fish, e coli
Why are genetics model organisms ideal
Low cost
Simple genome
Short generation time
What are some disprove theories
- Pangenesis (specific pieces of info travel from various parts of body to reproductive organs to embryo
- Inheritance of acquired traits
- Performationism (homunculus)
- Blending inheritance
Cell theory
All life composed of cells. cells arise from only cells.
Mendellian inheritance
traits are inherited according to specific principles proposed by mendel
Germ Plasm Theory
Proposed by August Weismann - cells in the reproductive organs carry complete set of genetic information that is passed to the egg and sperm
When was the first genome of bacteria sequenced?
1995
When was PCR created? Who created it?
1983, Mullis
