Mendel and the Pea Plant

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.

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

1. True

2. False

Q.

True breeding line is ___.

1. homozygous

2. heterozygous

3. hemizygous

4. isozygous

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.

When it concerns Mendel’s experiments, which among the following is the odd one out?

1. Flower colour - Purple/White

2. Pod colour - Green/Yellow

3. Seed colour - Yellow/Green

4. Endosperm colour - Green/Yellow

Q. Which amongst the following characters were not studied by Mendel in his experiments?

1. Height of the stem
2. Colour of the flower
3. Shape of the seed
4. Shape of the leaf

Q.

Mendel conducted experiments on ___.

1. Sweet Pea

2. Wild Pea

3. Pigeon Pea

4. Garden Pea

Q.

Which among the following are reasons for Mendel's success?

1. He applied statistical analysis and mathematical logic to problems in biology.

2. His experiments had a large sampling size.

3. He conducted experiments on successive generations of his test plants to confirm his inferences.

4. All of these.

Q.

Pea plants are more suitable than mice for Mendel's experiments, because pea plants can be self-fertilised, are easy to grow in large numbers and have a short life cycle.

1. True

2. False

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
