Question

Which graph represents selection that may lead to reduced variation in a population?

Answer 1

The frequency graph represents selection that may lead to reduced variation in a population.

Further Explanation:

The density of the population determines its growth rate. If the area is densely populated, the growth rate will decrease. The population size would decrease in approaching the carrying capacity of the human population is regulated by density-dependent factors. The natural selection will work as a selection mechanism in which the suitable allele gets selected, leading to an increase in the frequency of that particular allele. The frequency-dependent selection occurs when there is variability in the frequency of a phenotype and not the fitness.

The frequency graph illustrates a visual presentation of frequency count together information that is to be interpreted. They represent data to classify a range of rations. It gives a relative frequency and absolute distribution such as proportion or percentage in the form of histograms and charts. The information is displayed through plotting columns as the X and Y-axis to represent measure frequency and variable count.

Answer 2

A frequency graph can represent selection to illustrate population variation. 

Frequency graphs are used to represent data to identify a range of measure. It displays a visual illustration that presents frequency counts to make the information be interpreted more easily. It also shows an absolute distribution or relative frequencies like precentages or proportions. Frequency table or Frequency graph is the simplest method to show the number of occurrences of a particular characteristics. Histograms or bar charts are both displays of frequencies. This is done through plotting columns on a graph. It is usually written thru an X and Y axis which generally represents a measured variable and frequency count, respectively.
