Plant A will be the tallest.
Plant A will be the tallest.

Plant C will be the shortest.

Answer 1

In pea plants, the allele for tallness (T) is dominant over the allele for shortness (t).

• Plant A (tt) has two recessive alleles and will be short.
• Plant B (TT) has two dominant alleles and will be tall.
• Plant C (Tt) has one dominant allele and one recessive allele, which means it will also be tall, but not as tall as Plant B if we assume typical dominance and a possible height gradient.

Based on this information:

• Plant A will be the shortest because it has the recessive genotype (tt).
• Plant B will be the tallest because it is homozygous dominant (TT).
• Plant C will be tall due to the presence of one dominant allele (Tt), but not as tall as Plant B.

Thus, the most reasonable prediction from the options provided is: Plant C will be the shortest.
