According to Mendelism which character is showing dominance:
1. Terminal position of the flower
2. Green colour in the seed coat
3. Wrinkled seed
4. Green pod colour
Which one of the following traits of garden peas studied by Mendel was a recessive feature?
1. | Axial flower position |
2. | Green seed colour |
3. | Green pod colour |
4. | Round seed shape |
Given below are two statements:
Statement I: | Mendel studied seven pairs of contrasting traits in pea plants and proposed the Laws of Inheritance |
Statement II: | Seven characters examined by Mendel in his experiment on pea plants were seed shape and colour, flower colour, pod shape and colour, flower position and stem height |
In the light of the above statements, choose the correct answer from the options given below:
1. Statement I is incorrect but Statement II is correct.
2. Both Statement I and Statement II are correct.
3. Both Statement I and Statement II are incorrect.
4. Statement I is correct but Statement II is incorrect.
