Mendel and the Pea Plant

Q.

Who is regarded as the father of genetics?

1. Gregor Johann Mendel

2. Thomas Hunt Morgan

3. Jean-Baptiste Lamarck

4. Hugo de Vries

Q.

The title of the paper published by Mendel in 1856 was "Experiments in plant hybridization".

1. True

2. False

Q. Pea plants cannot be self fertilised and they have long life cycle.

1. True
2. False

Q.

Match the following characters with their contrasting traits in case of pea plants.

$\begin{array}{cc}ColumnI& ColumnII\\ \text{A. Stem height}& \text{1. Axial/terminal}\\ \text{B. Flower position}& \text{2. Round/wrinkled}\\ \text{C. Pod shape}& \text{3. Tall/dwarf}\\ \text{D. Seed shape}& \text{4. Inflated/constricted}\end{array}$

1. A - 1, B - 2, C - 3, D - 4

2. A - 3, B - 1, C - 4, D - 2

3. A - 3, B - 1, C - 2, D - 4

4. A - 4, B - 3, C - 2, D - 1

Q.

Mendel used true breeding pea lines for his experiments because -

1. True breeding lines are suitable for cross-pollination.

2. True breeding lines are suitable for self-pollination.

3. True breeding lines have undergone continuous self-pollination and keep showing stable trait inheritance for several generations.

4. True breeding lines possess hermaphrodite flowers.

Q. What is the scientific name of the plant used by Mendel in his classical hybridisation experiment?

1. Both a and b are correct
2. Lathyrus odoratus
3. Azadirachta indica
4. Pisum sativum

Q.

Mendel selected the pea plant for his experiments because:

A. It has a short life cycle

B. Possesses contrasting heritable characters

C. Self-fertilises and produces pure breeds

D. Cross-pollination produces fertile hybrids

1. A & B only

2. C & D only

3. B & C only

4. A, B, C & D
