- A plant is a kind of organism
- Tall height is a dominant trait in pea plants
- Short height is a recessive trait in pea plants
- Crossing a pure dominant organism with a pure recessive organism causes all their offspring to be heterozygous dominant
- Therefore, crossing a pure tall pea plant with a pure short pea plant causes their offspring to be tall pea plants

Therefore, crossing a pure tall pea plant with a pure short pea plant causes their offspring to be tall pea plants
Question
In pea plants, tall is dominant over short. What size pea plants will result when a pure tall plant is crossed with a pure short plant?
