Q1. Select the incorrectly matched combination of characters and contrasting traits studied by Mendel in the pea plant.
A Seed Colour: Yellow/green
B Seed Shape: Round/wrinkled
C Flower position: Axial/terminal
D Pod Colour: White/yellow Correct
Explanation
Mendel studied seven pairs of contrasting traits in pea plants. Seed colour as yellow or green is a correct pair, and seed shape as round or wrinkled is also one of his standard pairs. Flower position as axial or terminal is another correctly matched character-trait combination. Pod colour, however, was studied as green or yellow, not white or yellow. White belongs to flower colour in Mendel's list, where the contrast is violet or white. Therefore, pod colour as white/yellow is the incorrectly matched combination.
