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.
This quiz covers the basics of heredity, including the transmission of genes from parents to offspring and the role of genetics in determining phenotypic features.
