Question

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

Plant A: tt
Plant B: TT
Plant C: Tt
(1 point)

Plant A will be the tallest.

Plant A and Plant C will have similar heights.

Plant C will be the shortest.

Plant B and Plant C will have similar heights.

Answer 1

The most reasonable prediction based on the genotypes of the three plants is that Plant C will be the shortest. This is because Plant C has a heterozygous genotype (Tt), meaning it has one dominant and one recessive allele. In pea plants, the dominant allele (T) is associated with tall height, while the recessive allele (t) is associated with short height. Since Plant C only has one dominant allele, it is likely to be shorter than Plant B, which has two dominant alleles (TT).
