10 Questions
What is biometrical genetics?
Biometrical genetics is the study of the inheritance of quantitative traits and identifying the genetic determinants for variations in these traits.
Who laid the basis for understanding how variations are passed from parents to the next generation?
Mendel
What is the multiple-factor hypothesis?
The multiple-factor hypothesis is the idea that multiple factors contribute to the inheritance of quantitative traits.
Who pioneered the development of appropriate tools for biometrical analysis?
R.A. Fisher
What is the multiple factor theory?
The multiple factor theory is the idea that multiple factors contribute to the inheritance of quantitative traits and can be used as a basis for experimental design.
Match the following concepts with their correct descriptions:
Biometrical genetics = The study of the inheritance of quantitative traits and identification of underlying genetic determinants Multiple-factor hypothesis = The idea that multiple factors contribute to the variation of a trait R.A. Fisher = Scientist who pioneered in devising the appropriate tools for biometrical analysis Mendel = Scientist who laid the basis for understanding how variations are passed from parents to the next generation
Match the following key figures with their contributions to biometrical genetics:
Mendel = Laid the basis for understanding how variations are passed from parents to the next generation R.A. Fisher = Pioneered in devising the appropriate tools for biometrical analysis Other scientists in early 19th century = Advocated the multiple-factor hypothesis Scientists in collaboration with Fisher = Developed sufficient results to justify the multiple factor theory
Match the following terms with their definitions in the context of biometrical genetics:
Quantitative traits = Traits that can be measured and expressed numerically Genetic determinants = Factors that determine the expression of a trait in an organism's genetic makeup Biometrical mode of analysis = An essential approach for success in studying biometrical genetics Experiments based on multiple factor theory = Design of experiments that can give guidance to the process of arti
Match the following historical events with their significance in the field of biometrical genetics:
Mendel's experiments = Laid the basis for understanding the inheritance of variations Mendel's multiple-factor hypothesis = Clearly adumbrated the idea that multiple factors contribute to the variation of a trait R.A. Fisher's paper on human correlations (1918) = Early work that contributed to the development of appropriate tools for biometrical analysis Accumulated results = Justified the multiple factor theory as a basis for designing experiments in biometrical genetics
Match the following terms with their correct usage in the context of biometrical genetics:
Variations in traits = Quantified and studied in biometrical genetics Genetic determinants = Identified in biometrical genetics as the underlying factors for trait variations Multiple-factor hypothesis = Used to explain the variation of traits in the context of biometrical genetics Biometrical mode of analysis = Essential for success in studying biometrical genetics
