Question

Among the following characters, which one was not considered by Mendel in his experiments on pea?

• A. Stem – Tall or Dwarf
• B. Trichomes – Glandular or non-glandular
• C. Seed – Green or Yellow
• D. Pod – Inflated or Constricted

Answer 1

The Correct Option is B

To answer the question about which character was not considered by Mendel in his experiments on pea plants, we must first understand what characters Mendel actually studied.

Gregor Mendel conducted experiments on pea plants and observed seven different traits, each with two contrasting forms. They include:

• Stem height: Tall or Dwarf
• Flower Color: Violet or White
• Flower position: Axial or Terminal
• Pod shape: Inflated or Constricted
• Pod color: Green or Yellow
• Seed shape: Round or Wrinkled
• Seed color: Yellow or Green

Among the provided options, the option "Trichomes – Glandular or non-glandular" was not part of Mendel's original set of traits observed in his experiments with pea plants.

Let's break down why each option is correct or incorrect:

1. Stem – Tall or Dwarf: Mendel considered this trait in his experiments.
2. Trichomes – Glandular or non-glandular: This trait was not studied by Mendel.
3. Seed – Green or Yellow: Mendel observed this trait as part of his experiment.
4. Pod – Inflated or Constricted: This was also a trait observed by Mendel.

Therefore, the correct answer is Trichomes – Glandular or non-glandular, as it is the only trait among the options not studied by Mendel in his experiments.
