question 17

Multiple Choice

Many SNPs are regarded as "neutral" in the sense of having little or no effect on the likelihood of survival or reproduction of the different genotypes. Could you ever say for certain that a particular SNP is "neutral"?

• A)Yes, if the polymorphism is in noncoding DNA.
• B)Yes, if the polymorphism is in a transposable element.
• C)Yes, if the polymorphism results in synonymous codons.
• D)No, because any effect may be too small to detect.

Definitions:

Confounds

Variables that researchers fail to control or eliminate, which can cause a misunderstanding of the causal relationship in a study.

Operational Definitions

Clearly defined criteria or measures used to describe and quantify a concept or variable in research.

Conceptual Replicability

refers to the extent to which research findings can be confirmed or supported through studies with similar conceptual frameworks but different methods.

External Validity

Describes the extent to which research findings can be generalized or applied to settings, populations, or times beyond the scope of the original study.
