Question

Among the following characters, which one was not considered by Mendel in his experiment on pea?
A. Pod- inflated or constricted
B. Stem- tall or dwarf
C. Trichomes- glandular or non-glandular
D. Seed- green or yellow

Answer 1

Hint: Mendel conducted artificial hybridization or say cross pollination using true breeding pea lines for his work. In his experiments with peas, Mendel carefully bred male and female plants and observed traits in offspring. His work showed that an organism inherits genetic material that determines physical traits from both the male and female parent.

Complete answer:
Mendel studied seven pairs of contrasting traits. That are
Stem - tall(Dominant) or dwarf(recessive)
Pod shape- inflated(Dominant) or constricted(recessive)
Seed colour- yellow(Dominant) or green(recessive)
Flower colour- violet(Dominant) or white(recessive)
Flower position- terminal(recessive) or axial(Dominant)
Pod colour- green(Dominant) or yellow(recessive)
Seed shape- round(Dominant) or yellow(recessive)
In a dissimilar pair one member of the pair dominates the other recessive one.

Additional information:
Mendel selected garden pea (Pisum Sativum) for the following reasons:-
It is an annual plant with a short life span and gives results within 3 months.
The plant can be easily grown and does not require any additional care after the time of pollination.
F1 hybrids are fertile.
Seven pairs of contrasting characters easily detectable.
True breeding self pollination.

Hence, the correct option is option C i.e. trichomes- glandular or non- glandular.

Note:- Mendel's work was not established for a time being due to following reasons-When he presented his work to other scientists he did not communicate it well so they did not really understand it, It was published in a scientific journal that was not well known so not many people read it, and He could not explain the science behind why characteristics were inherited.
