Question

State the opposite traits for each of the characters of flowers of the pea plant chosen by Mendel for his experiment. &ldquo;For developing the scientific ideas on heredity the experiments performed by Mendel on pea plants are epoch-making&rdquo;- Mention three reasons behind his success in performing the experiment.

Accepted Answer

The acquiring of genetic traits or characteristics by their offspring is known as Inheritance. Both parents contribute equally to the inheritance of traits in humans. Gregor Mendel studied the law of inheritance in 1860 and conducted an experiment on pea plants. He started cultivating pea plants and observed their inheritance pattern from one generation to another. The observation leads to the discovery of three laws of inheritance which are known as Mendel’s Law of Inheritance.

Mendel began his investigation with a pair of pea plants with two contrasting traits, i.e., one tall and another dwarf. He observed their pattern of inheritance. Similarly, he investigated pairs of pea plants with one contrasting trait. Mendel studied these seven characters that consist of contrasting traits:

Stem height: Tall/dwarf
Seed shape: Round/wrinkled
Seed color: Yellow/green
Pod color: yellow/Green
Flower position: terminal/Axial
Flower color: Violet/white
Pod shape: constricted/Inflated

Three reasons for success of Mendel’s experiment are given below:

Took pea plants that are self pollinating and has contrasting characters.

Studied only one character of a hybrid at a time.

Kept accurate quantitative and qualitative accounts.
