A tall pea plant with round seeds (TTRR) is crossed with a short pea plant with wrinkled seeds (ttrr). The generation will be:
A tall pea plant with round seeds (TTRR) is crossed with a short pea plant with wrinkled seeds (ttrr). The generation will be:
Options
100% tall with round seeds
Analysis & Explanation
Mendel's experiments show that when a tall pea plant with round seeds (TTRR) is crossed with a short pea plant with wrinkled seeds (ttrr), the F1 generation will be 100% tall with round seeds. This is because the tall trait (T) is dominant over the short trait (t), and the round seed trait (R) is dominant over the wrinkled seed trait (r).
Common Mistakes
- 1thinking that the F1 generation will be a mix of tall and short plants
- 2thinking that the F1 generation will have a mix of round and wrinkled seeds
Interesting Facts
