Question

Which of the following is not a correct dominant-recessive trait pair of Pisum sativum?

Answer 1

Mendel selected pea plant for his experiments. Pea plants had a lot of different characters. Mendel selected seven characters having contrasting traits in pea plants

$\begin{array}{ccc}\text{Dominant trait}& \text{Recessive trait}& \text{Character}\\ \text{Tall Plant}& \text{Short Plant}& \text{Plant Height}\\ \text{Violet Flower}& \text{White Flower}& \text{Flower Colour}\\ \text{Axial Flower}& \text{Terminal Flower}& \text{Position of Flower}\\ \text{Green Pod}& \text{Yellow Pod}& \text{Pod Colour}\\ \text{Inflated Pod}& \text{Constricted Pod}& \text{Pod Shape}\\ \text{Yellow Seed}& \text{Green Seed}& \text{Seed Colour}\\ \text{Round Seed}& \text{Wrinkled Seed}& \text{Seed Shape}\end{array}$

$\text{Incorrect combination}$
Yellow-green are dominant-recessive traits of seed colour and not pod colour. Hence, among the given options, option B with pair of ‘Yellow-green pod colour, Round-wrinkled seed shape’ is incorrect.
