Question

analysis of the alleles present in each population was performed in two different ways, and the data were combined to calculate the frequencies (table 1). table 1. frequency of opsin alleles in three populations of a small primate

	frequency (±2se.)
allele 1	0.60 (.05)	0.80 (.06)	0.25 (.02)
allele 2	0.15 (.02)	0.05 (.01)	0.45 (.03)
allele 3	0.25 (.02)	0.15 (.02)	0.30 (.02)

(a) describe one measure of evolutionary fitness.
note on your ap exam, you will handwrite your responses to free - response questions in a test booklet
the allele frequency in a population.
(b) using the template, construct an appropriately labeled graph to represent the data in table 1. based on the data, determine whether there is a significant difference in the frequency of each allele among the three primate populations.

Explanation:

(a) One measure of evolutionary fitness is reproductive success. It is the number of viable offspring an organism produces over its lifetime. Organisms with higher reproductive success are more likely to pass on their genes to the next - generation, influencing the allele frequencies in the population over time.
(b) To construct a graph, we can use a bar - graph with the x - axis representing the three populations (Population 1, Population 2, Population 3) and the y - axis representing the frequency of alleles. For each allele (Allele 1, Allele 2, Allele 3), we will have three bars (one for each population). To determine if there is a significant difference in allele frequencies among the populations, we can perform a statistical test such as a chi - square test. If the p - value from the test is less than 0.05, we can conclude that there is a significant difference in the frequency of the allele among the populations.

Answer:

(a) Reproductive success, which is the number of viable offspring an organism produces over its lifetime.
(b) Construct a bar - graph with populations on x - axis and allele frequencies on y - axis. Perform a chi - square test to determine if there is a significant difference in allele frequencies among populations. If p < 0.05, there is a significant difference.
