Study Notes
Genetics Basics
- Gregor Mendel is considered the father of modern genetics, a foundational figure in the field.
Cell Division and Inheritance
- Mitosis is the process by which gametes (sex cells) are produced in an organism.
Autosomal Dominant Traits
- Autosomal dominant traits are always expressed when an individual inherits one copy of the dominant allele, showcasing the dominant nature of these traits.
Inheritance Patterns
- Polygenic inheritance involves the interaction of multiple genes, not just two, highlighting the complex nature of genetic interactions.
Genotype and Phenotype
- The genotype of an individual determines their phenotype, illustrating the direct relationship between genetic makeup and physical characteristics.
Key Figures in Genetics
- Gregor Mendel is known as the father of modern genetics.
Cellular Processes
- Mitosis is the process by which gametes are produced.
- Meiosis is not the process by which somatic cells are produced.
Inheritance Patterns
- Autosomal dominant traits are always expressed when an individual inherits one copy of the dominant allele.
- Autosomal recessive inheritance requires an individual to inherit two copies of the recessive allele to express the trait.
- Polygenic inheritance involves the interaction of multiple genes.
Genotype and Phenotype
- The genotype of an individual determines their phenotype.
Gregor Mendel's Work
- Gregor Mendel's work on genetics was not widely recognized and accepted during his lifetime.
Environmental Influence
- The environment does influence the phenotype of an individual.
