To analyze the heights of the three pea plants based on their genotypes:
- Plant A (tt): This plant is homozygous recessive for the height allele. In pea plants, the recessive phenotype (tt) is typically shorter.
- Plant B (TT): This plant is homozygous dominant and will show the dominant phenotype (tall), making it the tallest.
- Plant C (Tt): This plant is heterozygous and will also show the dominant phenotype (tall), similar to Plant B but typically not as tall as the homozygous dominant plant.
Based on this genetic information, we can make the following observations:
- Plant A (tt) will be the shortest.
- Plant B (TT) will be the tallest.
- Plant C (Tt) will be tall, but probably not as tall as Plant B.
Therefore, the most reasonable prediction among the options provided is:
Plant A will be the tallest. - (Incorrect)
Plant C will be the shortest. - (Incorrect)
Plant B and Plant C will have similar heights. - (Incorrect)
Plant A and Plant C will have similar heights. - (Incorrect)
The accurate prediction is: Plant B will be tallest, Plant A will be the shortest, and Plant C will be between them in height.
Thus, among the given responses, none of them are perfectly stated; the best choice would have pointed out that Plant B is the tallest, followed by Plant C, with Plant A being the shortest.
In conclusion, if forced to choose an interpretation based on "similar heights," the closest choices should reference the comparative heights, acknowledging Plant A as the shortest and Plant B as the tallest, but since those were not options, none match accurately.
