Study Notes
Heredity
- Living organisms are identified based on their phenotypic features, which are mostly determined by their genetic constitution.
- The similarity between family members is due to the inheritance of characteristics from parents to progeny.
- The difference between individuals of a family is the manifestation of variation.
Heredity as Transmission of Genes from Generation to Generation
- Heredity is the transmission of genes from parents to offspring, guaranteeing the characters in the offspring.
- Variation that is inherited through a change in gene structure should be stable and capable of transmission from generation to generation.
Variation and its Inheritance
- Variations can be classified at various levels, including macroscopic level, morphological variation, physiological variation, and psychological variation.
- Examples of macroscopic variations include free ear lobe and non-tolling of tongue.
- Morphological variations include variations in the morphology of individuals, such as free ear lobe and attached ear lobe.
Scientists behind the Discovery of Inheritance
- Gregor Mendel is known as the "father of genetics" due to his contributions to the study of inheritance.
- Mendel carried out experiments with pea plants (Pisum sativum) to elucidate the principles of inheritance.
Heredity and Common Genetic Diseases
- Heritable variation is a permanent change in the genes of an organism, which may lead to the generation of new characters within succeeding generations.
- Heritable variations can result from damage to DNA, genetic alteration, or environmental pressure.
- Only heritable variations are important for evolution.
Discovery of Principles of Inheritance
- Gregor Mendel discovered the laws of inheritance, including the Law of Segregation and the Law of Independent Assortment.
- The term "gene" was coined by Johannsen in 1909.
