Question

Which of the following is a recessive trait for garden pea plant?

• A. Round seed
• B. Constricted pod
• C. Tall plant
• D. Violet flower

Answer 1

The Correct Option is B

The study of inheritance in garden pea plants, explored by Gregor Mendel, revealed the distinction between dominant and recessive traits. Mendel identified several traits in garden pea plants, where each has a dominant and a recessive form. In peas, the traits with their typical dominant-recessive pairings include:

• Seed shape: Round (dominant) vs. Wrinkled (recessive)
• Pod shape: Inflated (dominant) vs. Constricted (recessive)
• Plant height: Tall (dominant) vs. Dwarf (recessive)
• Flower color: Violet (dominant) vs. White (recessive)

To answer the question, "Which of the following is a recessive trait for garden pea plant?" we identify the options: Round seed, Constricted pod, Tall plant, Violet flower.

• Round seed is a dominant trait compared to wrinkled.
• Constricted pod is the recessive trait opposite to the dominant inflated pod trait.
• Tall plant is a dominant trait over dwarf.
• Violet flower is dominant compared to white flowers.

Therefore, the correct answer is:

Constricted pod

Answer 2

In Mendelian genetics, certain traits exhibit dominant and recessive patterns of inheritance. For the garden pea plant, several traits were studied by Mendel. Among the traits listed:

• Round seed is a dominant trait.
• Tall plant is a dominant trait.
• Violet flower is a dominant trait.
• Constriction of the pod is a recessive trait.

In Mendel's experiments, the recessive trait will only appear if both alleles are recessive (homozygous recessive). For the constricted pod trait, the pod will appear constricted only if the plant is homozygous recessive.
