To predict the heights of the three pea plants based on their genotypes, it's important to consider the nature of the alleles involved—specifically, whether the allele for height is dominant or recessive.
Assuming we have the following genotypes:
- Plant A: Homozygous dominant (TT)
- Plant B: Heterozygous (Tt)
- Plant C: Homozygous recessive (tt)
In this scenario:
- Plant A (TT) will be tall.
- Plant B (Tt) will also be tall, as the presence of at least one dominant allele (T) leads to a tall phenotype.
- Plant C (tt) will be short, as it carries two recessive alleles.
Based on these genotypes, we can make the following predictions about their heights:
- Plant A will be tall.
- Plant B will also be tall, similar in height to Plant A.
- Plant C will be the shortest.
So, the most reasonable prediction based on the information is: Plant C will be the shortest.
