Many Traits of Organisms, Such as Body Form and Color

question 22

Multiple Choice

Many traits of organisms, such as body form and color, are controlled by specific proteins, in turn controlled by the DNA genetic sequence of nucleotides. The genetic control of color, as in aphids, does not usually shift during the life of an organism. Researchers found that some specific aphid populations shift from an original red coloration to a green coloration. Genetics could be a factor, if some programmed shift could be identified. Environmental conditions of the living and nonliving habitat could be a factor. Either way, the chemistry and observed changes of pigment molecules in the aphids can be studied with the scientific method.
-Researchers noted that only few aphids changed color to green from their original red.This is an unusual observation among any animals.What research question came out of the observations?

• A) Will green aphids change their color to red, or remain green as they age?
• B) Is the color shift of certain aphids due to genetics or some other factor?
• C) The color shift of certain aphids is due to genetics within the species.
• D) Do other aphids change colors as they age?

Definitions:

Variance

A measure of the spread or dispersion of a set of data points, indicating how much the data varies from the average of that set.

Outliers

Observations in a dataset that significantly differ from the other data points, often indicating variability or errors.

1.5*IQR

A statistical calculation used to identify outliers. It involves multiplying the interquartile range (IQR) by 1.5 and applying this value above the upper quartile and below the lower quartile.

3*IQR

A statistical range calculated as three times the interquartile range (IQR), used to identify outliers by delineating the boundaries beyond which data points are considered exceptional.
