What are the characteristics of a garden pea?

Mendel looked at seven different characteristics of the pea plants he experimented with.

These were:

- flower colour (white or purple)

- flower position (axil or terminal)

- stem length (short or long)

- seed shape (round or wrinkled)

- seed colour (green or yellow)

- pod shape (inflated or constricted)

- pod colour (green or yellow)

He illustrated that some traits are hereditary, they are passed on to the next generation.
