"What is the relationship between reliability and validity? Is it possible for a measure to be reliable and invalid? Conversely,

is it possible for a measure to be unreliable and valid?"
Biology

Answer:

Explanation:

Reliability has to do with how consistent the measures in an experiment are, this has to do with how reproduceable those measures are under the same circumstance. While validity has to do with the correctness or accuracy of measures in an experiment.

It is possible for a measurement to be unreliable and yet valid because even reliable (consistent measures) may not always necessarily be correct. Experiments involving living things sometimes deviate from normal measures due to several factors that cannot be explained but that does not mean that the results are invalid.

Identify the term by its definition:
Katena32 [7]

Answer:

1. Cytogenetic mapping.

2. Linkage mapping.

3. Physical mapping.

Explanation:

1.<u> Cytogenetic mapping - Gene localization using microscope.</u>

A cytogenetic mapping is defined as the visual appearance of genes when seen by using microscope. The genes are stained and seeing under microscope that shows visually distinct regions, called dark and light bands and provide unique appearance to the genes.

2. <u>Linkage mapping - recombination distance s measured using genetic crosses. </u>

Linkage mapping is done using linkage analysis by observing the genes linked to the offspring. It do not show physical distances but only shows genetic distances and how the two genes inherited together.

3. <u>Physical mapping - Determine nucleotide sequence distance using DNA cloning.</u>

Physical mapping is a technique by which physical distance between DNA base pairs can be evaluated with the help of DNA makers and also determine DNA base pairs sequences with high accuracy.
