Question

Which one of the following traits of garden pea studied by Mendel was a recessive feature?

• A. Green seed colour
• B. Green pod colour
• C. Round seed shape
• D. Tall height

Answer 1

The correct option is A Green seed colour

Mendel selected 14 different varieties of the pea and grouped them into seven pairs. Each pair was considered for a specific trait (characteristic) such as flower colour or seed shape or stem length, etc. The two members of each pair showed contrasting forms of the chosen trait, e.g., in a pair selected for stem length, one variety had a tall stem (6-7 feet tall) while the other had a dwarf stem. These seven pairs of contrasting traits are as follows:

Form of seed- Round (R) and Wrinkled (r)

Colour of cotyledons- Yellow (Y) and Green (y)

Colour of seed coat- Coloured (C) and White (c)

Form of pod- Inflated (I) and Constricted (i)

Colour of pod- Green (G) and Yellow (g)

Position of flower- Axial (A) and Terminal (a)

Height of plant (Length of stem)- Tall (T) and Dwarf (t)
