Mendel's experiments

F1 generation

tall trait

round seed trait

1. $thinking that the F1 generation will be a mix of tall and short plants$
2. $thinking that the F1 generation will have a mix of round and wrinkled seeds$

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).

$Mendel's experiments were the first to demonstrate the principles of inheritance$

$Mendel's work was not widely recognized until after his death$
