Without being able to see the actual distribution graph for wild lupines, I can provide a general guideline on how to evaluate the statements based on typical data you might find in such graphs.
-
All flower color alleles have an equal chance of appearing in the next lupine generation.
- This is unlikely if the graph shows a significant skew toward certain colors, indicating that not all alleles are equally represented.
-
There are fewer pink and white lupines due to drought.
- This could be supported if the graph shows a decline in those colors at the same time as a noted drought condition, but would require additional evidence linking the colors to the environmental condition.
-
Conditions in the environment favor purple lupines.
- This could be a defendable statement if the graph clearly shows a larger population of purple lupines compared to other colors, suggesting that purple is the most successful flower color under current conditions.
-
The population has only one allele for flower color.
- This statement would be unsupported if the graph shows multiple distinct color categories, indicating the presence of multiple alleles.
Based on standard interpretations, if the graph indicates a predominance of purple lupines over others, the statement "Conditions in the environment favor purple lupines." could likely be defended using the data from the graph.
