Pea plants cannot be self fertilised and they have long life cycle.
Pea plants are more suitable than mice for Mendel's experiments because pea plants can be self-fertilised, are easy to grow in large numbers and have a short life cycle.
Mendel selected the pea plant for his experiments because:
A. It has a short life cycle
B. Possesses contrasting heritable characters
C. Self-fertilised and produces pure breeds
D. Cross-pollination produces fertile hybrids
