Question

Which one of the following pairs consists of both recessive traits in Pisum sativum as studied by Mendel?

• A. Dwarf plant and axil flower position
• B. Constricted pod shape and round seed shape
• C. Green seed colour and terminal flower position
• D. White flower and yellow seed colour

Answer 1

The correct option is C Green seed colour and terminal flower position

Mendel reveals that there are seven different traits:

1. Pea shape ( round-dominant; wrinkled -recessive)
2. Pea colour (Green - dominant; Yellow - recessive)
3. Pod shape (constricted - dominant; inflated - recessive)
4. Pod colour (green -dominant; yellow - recessive)
5. Flower colour (Purple -dominant; White -recessive)
6. Plant size (Tall - Dominant; Dwarf - recessive)
7. Position of flowers (Axial - Dominant; Terminal - recessive)
