According to mendelism which character is showing dominance?
- Green colour in seed coat
- Wrinkled seed
- Terminal position of flower
- Green pod colour
Answer
(4) Green pod colour
Solution
As per NCERT (seven pairs of contrasting traits in pea studied by Mendel):
Pod colour – green (dominant), yellow (recessive).
Seed shape – round (dominant), wrinkled (recessive).
Flower position – axial (dominant), terminal (recessive).
Seed coat colour – coloured / grey (dominant), white (recessive); green is the recessive colour of the cotyledons (seed colour), not a dominant trait.
∴ Green pod colour is the dominant character.
