Q22.3-2ITD - Campbell Biology

Question

Explain how the types of data the researchers chose to collect enabled them to test their prediction.

Step-by-Step Solution

Answer

The number and area of colored spots are located on a graph, and these patterns are observed in the source and transplanted population of the guppy (Poecilia reticulata) to test the prediction.

Step 1: Researcher

The investigative personality that makes a person conduct research to learn something new and understand a phenomenon under the study is called a researcher. 

 

The several study types are experimental, case, correlation, and longitudinal studies. The different characteristics of a researcher are logical, empirical, and cyclical.

Step 2: Poecilia reticulata

The term Poecilia reticulata refers to a prolific fish species known for its popularity to be considered an aquarium fish.

 

These fish (guppies) can bear a wide range of water conditions and related environments.

Step 3: Data collection to test prediction

The distinct data type chosen by the researcher for testing the prediction of the natural selection process are guppies with color spots and areas covered by this colored-pattern. 

 

This testing prediction by the researcher provides a quantitative method for comparing brightness due to genes expressed in the guppies’ population.
