Question

One of the following did not constitute the seven contrasting pairs of characters studied by Mendel:

• A. Height of the plants
• B. Shape of the leaves
• C. Shape of a pod
• D. Colour of a pod

Answer 1

The correct option is B Shape of the leaves

Mendel selected Pisum sativum as the experimental plant for genetics. He chose seven characters of the pea plant. They are:

$\begin{array}{cccc}\text{S.No.}& \text{Character}& \text{Dominant}& \text{Recessive}\\ 1.& \text{Stem height}& \text{Tall}& \text{Dwarf}\\ 2.& \text{Flower colour}& \text{Violet}& \text{White}\\ 3.& \text{Flower position}& \text{Axial}& \text{Terminal}\\ 4.& \text{Pod shape}& \text{Full}& \text{Constricted}\\ 5.& \text{Pod colour}& \text{Green}& \text{Yellow}\\ 6.& \text{Seed shape}& \text{Round}& \text{Wrinkled}\\ 7.& \text{Seed colour}& \text{Yellow}& \text{Green}\end{array}$

Shape of the leaves was not studied by Mendel. So, the correct option is b.
