In four o’clock plants, there are three phenotypes for flower color, but only two alleles. The table shows both the expected and observed numbers of plants of each flower color in a population of 1,000. The graph shows this:

Phenotypes Number Expected Number observed

Red Flowers: 105 173

Pink flowers: 484 343

White flowers: 411 484

Which statement best explains the results in the table?

1. The population is in equilibrium because the total number of plants expected and observed was about the same.

2. The population evolved because the frequency of the alleles and the genotypes changed.

3. The frequency of the alleles and genotypes in the population changed because of gene flow.

4. The observed frequency of the phenotypes is different from the expected frequency because some alleles mutated.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
