Quantitative traits - Study guides, Class notes & Summaries

Gene Determination correct answer: the idea that our genes solely determine who we are example: Huntingdon's disease, and sickle cell anemia both depend on genes did do genes determine everything? correct answer: NO, - alcoholism is not determined by genes complex traits = ? correct answer: Mendelian trais - complex traits do not follow a simple mendelian pattern of inheritance Mendelian traits correct answer: characteristics that are influenced by alleles at only one g...

Qualitative traits Ans: controlled by one or a few loci; discrete phenotypes (eye colour, coat colour, seed colour, seed texture, blood type, colourblindness etc) Quantitative traits Ans: controlled by multiple loci (also called polygenic traits); continuous phenotypes (height, weight, racing speed, milk yield, temperature, intelligence, temperament, schizophrenia - threshold trait) --> the range is measured as variation --> many loci contributing to the phenotype P = G + E An...

3. REVEALING TRADE-OFFS: THE USE OF MULTIVARIATE QUANTITATIVE GENETICS 3.1. Life-History Trade-Offs and Genetic Correlations The existence of trade-offs between different components of fitness is fundamental to much of life-history theory. If these constraints are to affect evolutionary processes, which evolutionary ecologists typically assume they will, they must have a genetic basis, requiring the action of either antagonistic pleiotropy or linked genes with antagonistic effects, and the...

Macroevolution - Answer Evolutionary change above the species level. Ecological species concept - Answer identifies species in terms of their ecological niches, focusing on unique adaptations to particular roles in a biological community Postzygotic - Answer Barriers that prevent the hybrid zygote from becoming a fertile adult. The theory of gradualism - Answer Profound geological changes took place through the cumulative effect of slow but continuous processes identical to ...

Simply-Inherited Traits Correct Answer: traits affected by only a few genes qualitative or categorical affected little by environment Quantitative Correct Answer: measured with numbers Polygenic Traits Correct Answer: Affected by many genes with no gene having an overriding influence. - EX: Growth rate, milk production, ribeye area Typically quantitative or continuous in expression. - Phenotypes are usually described by numbers Greatly influenced by environment Examples of Sim...

1. Which of the following groups would be best served by the development of a scientific base for nursing practice? A) Nursing administrators B) Practicing nurses C) Nurses' clients D) Health care policymakers Ans: C Feedback: Nursing research is systematic inquiry designed to develop trustworthy evidence about issues of importance to nurses and their clients. Nurse leaders recognize the need to base specific nursing decisions on evidence indicating that the decisions are clinically app...

How many loci are involved in quantitative traits? Ans: 10s, 100s, 1,000s of loci What do the many loci involved in a quantitative trait do? Ans: Most have a small effect on the overall function, some have larger parts and can be found. QTL is? Ans: quantitative trait loci QTL Detection Ans: Finding a polymorphism in the genome that is associated with a difference in phenotype. Polymorphism Ans: 2 or more variant forms of a specific dna structure 2 SNP Ans: single nucleotide poly...
