Question

Which trait will contrast with the green color?
(A)Tall plant
(B)Yellow colour
(C)Round seed
(D)Wrinkled seed

Answer 1

The traits are always in a pair and both traits will contribute to a particular characteristic i.e colour trait will be paired with colour trait and the height trait will be paired with another height trait i.e, for example, tall and dwarf.

Complete answer:
The trait that will contrast with the green colour is the yellow colour. Mendel selected pea plants for his experiments and found seven traits in the plants. One of them is the color of the seed. The colour of the seed is found to be of two types i.e green colour and yellow colour.

Additional Information: The seven traits that Mendel studied in pea are listed below:
-Type of seed shape i.e whether the seed is– round or wrinkled
-Seed color – yellow or green
-Colour of flower – purple or white
-Pod shape – inflated or constricted
-Pod color – green or yellow
-Position of flowers – axial or terminal
-Length of stem – tall or dwarf
Mendel presented his results in the year 1865 while experimenting on nearly 30,000 pea plants to the
local natural history society, his results were based on the patterns he observed, the counting data he
collected, and the mathematical analysis of his results.
So, the correct answer is ‘Yellow colour’.

Note: Mendel selected garden pea for his experiments due to the following characteristics:
- The first and the most important point which was there in the mind of Mendel is that garden pea
needs a shorter lifetime and are the plants that are easier to take care of.
- They are self-pollinating, and thus, self and cross-pollination can easily be performed.
- The various physical characteristics were easy to recognize and study.
- The flowers of this plant are bisexual.
