Question

How many pairs of contrasting characters in pea
pod were chosen by Mendel?
(a) 2 (b) 3
(c) 4 (d) 7

Answer 1

Answer:

Seven pairs of contrasting character in pea pod were chosen by mendal.

Seven contrasting character is as follow

1. Length of plants

2. Flower position.

3. shape of pod

4. colour of pod.

5. shape of seed

6. colour of cotyledon

7. colour of flower.

These all characters are present on different different chromosome numbers . These are the 1st, 4th, 5th and 7th.

From this constricting character some were dominant aur some were recessive. .

Answer 2

7 pairs of contrasting characters in pea

pod were chosen by Mendel.

* The 7 pairs of characters are:

1. Colour of flower- purple and white

2. Colour of pod- yellow and green

3. Colour of seed- yellow and green

4. Shape of seed- round and wrinkled

5. Shape of pod- inflated and constricted

6. Length of stem- long and short

7. Position of flower- axial and terminal

* Mendel performed both monohybrid cross and dihybrid cross using the given characters.

Monohybrid- taking one set of characters at a time

Dihybrid- taking two sets of characters at a time.
