Test: Morphological Variations - JAMB MCQ

Height is a trait that shows a range of values across the human population, making it an example of continuous variation.

Color variations in plants and animals are influenced by environmental conditions, such as light intensity and temperature, genetic constitution, which determines the presence of pigments, and habitat-specific adaptations that favor certain coloration for camouflage or mate attraction.

Measuring heights and weights of pupils of the same age group provides valuable information about their growth and development patterns, allows for comparisons within the same age group, and helps identify individual differences in physical attributes.

A histogram is commonly used to plot the frequency distribution of continuous variables like heights and weights. It consists of bars that represent the frequency of data falling within specific intervals.

A histogram is most appropriate for visualizing the frequency distribution of continuous data, which includes variables like heights and weights that can take any value within a range.

Color variation in mammals can be observed in the coat patterns, such as spots or stripes, seen in animals like leopards, tigers, or cheetahs.

The primary purpose of classifying fingerprints is to identify individuals. Fingerprints are unique to each person, and their classification allows for their use in identity detection and forensic investigations.

Arch fingerprints have ridges that enter from one side of the finger and exit on the other side, forming a consistent arch shape. They are one of the three major ridge patterns used in fingerprint classification, along with loops and whorls.

Genetic constitution refers to the genetic makeup of an individual, inherited from their parents. It plays a significant role in determining various morphological variations, such as hair and eye color, but it does not directly determine an individual's height, weight, or habitat preference.

The environment can exert selective pressures on individuals, favoring traits that enhance survival and reproduction. These selective pressures can lead to morphological variations within a population over time.
