Question
In the given options which is a dominant trait?
Wrinkled seed
Dwarf plant
Green seed color
Yellow seed color
Wrinkled seed
Dwarf plant
Green seed color
Yellow seed color
Hint:
Color of the dominant pea seeds.
The correct answer is: Yellow seed color
- Gregor Mendel developed the law of inheritance
- The scientific explanation for heredity was explained by him
- An experiment was conducted on garden peas
- 7 different phenotypes or physical appearances were discussed
- A cross was made between two plants: one dominant and one recessive
- The dominant and recessive plants showed contrasting phenotypes
- The traits exhibited by both plants are as follows:
Character
Dominant
Recessive
Seed shape
Smooth
Wrinkled
Seed color
Yellow
Green
Flower color
Purple
White
Pod shape
Inflated
Constricted
Pod color
Green
Yellow
Flower position
Axial
Terminal
Stem length
Tall
Dwarf
| Character | Dominant | Recessive |
| Seed shape | Smooth | Wrinkled |
| Seed color | Yellow | Green |
| Flower color | Purple | White |
| Pod shape | Inflated | Constricted |
| Pod color | Green | Yellow |
| Flower position | Axial | Terminal |
