theory of inheritance
Definition
Noun: 1. In biology, a theory or set of principles that explains the mechanisms and patterns by which traits, characteristics, or genetic information are passed from one generation (parents) to the next (offspring).
Usage
This term is used in scientific contexts, primarily in biology and genetics, to discuss formal explanations for the phenomenon of heredity. * The theory of inheritance proposed by Gregor Mendel forms the foundation of modern genetics. * Before DNA was understood, scientists debated various theories of inheritance.
Advanced Usage
- The term is often used historically to contrast different scientific models, such as the theory of inheritance based on Mendelian genetics versus earlier ideas like the blending theory of inheritance.
- It can be part of discussions on the evolution of biological thought: "The modern theory of inheritance integrates Mendelian principles with molecular biology."
Variants and Related Words
- Inheritance (n): The process or act of receiving genetic material or traits from ancestors.
- Mendelian inheritance (n): A specific theory of inheritance based on the principles of segregation and independent assortment of genes.
- Particulate theory of inheritance (n): The concept, central to Mendelian genetics, that hereditary information is passed on in discrete units (now called genes).
Synonyms
- Heredity theory
- Genetic theory
Related Phrases
- Laws of inheritance: Often refers specifically to Mendel's principles, which are a core component of his theory of inheritance.
- Mechanism of inheritance: Focuses more on the specific biological processes (e.g., chromosomal segregation) rather than the overarching explanatory framework.
Noun
-
(biology) a theory of how characteristics of one generation are derived from earlier generations
