Put all the candies used in Problems 41 back into a single mound and then divide them into two piles, being sure that the frequencies of each color are the same in each pile. Make a note of the starting frequency of each color. Label one pile 'male' and the other pile 'female.' Compare the starting frequency of each color with the frequency after drawing. Describe the observed differences and identify the evolutionary mechanism this exercise best emulates.

Key Concepts

Genetic Drift

Genetic drift is a mechanism of evolution that refers to random changes in allele frequencies within a population. It is particularly significant in small populations, where chance events can lead to large fluctuations in genetic variation. This concept is crucial for understanding how certain traits may become more or less common over generations, independent of natural selection.

Allele Frequency

Allele frequency is the proportion of a specific allele among all allele copies in a population. It is a key measure in population genetics, as it helps to quantify genetic diversity and the genetic structure of populations. Tracking changes in allele frequencies over time can provide insights into evolutionary processes and mechanisms.

Sexual Selection

Sexual selection is a form of natural selection where individuals with certain inherited traits are more likely than others to obtain mates. This can lead to the development of secondary sexual characteristics and can influence allele frequencies in a population. Understanding sexual selection is essential for analyzing how certain traits may be favored in one sex over the other, impacting overall genetic diversity.
