Study Notes
Basic Unit of Heredity
- The basic unit of heredity is a gene.
- Genes are segments of DNA that code for specific traits.
Genetic Makeup
- The term for the genetic makeup of an organism is genotype.
- Genotype refers to the specific combination of alleles an organism possesses.
Father of Genetics
- Gregor Mendel is known as the "Father of Genetics".
- Mendel conducted groundbreaking experiments with pea plants, laying the foundation for our understanding of inheritance.
Law of Independent Assortment
- The law of independent assortment states that each pair of alleles segregates independently of other pairs during gamete formation.
- This means that the inheritance of one trait does not influence the inheritance of another trait.
Autosomal Recessive Disorders
- Autosomal recessive disorders are characterized by the need for two copies of the recessive allele for the disorder to be expressed.
- These disorders often skip generations and are more likely to appear among siblings
Pleiotropy
- Pleiotropy describes the phenomenon where a single gene influences multiple, seemingly unrelated phenotypic traits.
- This means that a mutation in a single gene can lead to a range of diverse effects on an organism's appearance, physiology, and behavior.
