Use the table to answer the question

Question

Plant A
tt

Plant B
TT

Plant C
Tt

The table shows the genotypes of three pea plants for the allele for height. Which prediction about the three plants is most reasonable?

Plant B and Plant C will have similar heights

Plant C will be the shortest

Plant A will be the tallest

Plant A and Plant C will have similar heights

Answer 1

In pea plants, the allele for tall height (T) is dominant over the allele for short height (t).

• Plant A has the genotype "tt," which means it has two recessive alleles and will be short.
• Plant B has the genotype "TT," which means it has two dominant alleles and will be tall.
• Plant C has the genotype "Tt," which means it has one dominant allele and one recessive allele, and will also be tall.

Given this information, we can make the following predictions about their heights:

1. Plant B (TT) and Plant C (Tt) will both be tall.
2. Plant A (tt) will be the shortest.

Based on these predictions, the most reasonable answer is:

Plant B and Plant C will have similar heights (both will be tall).
