Question

1. describe mendels first experiment.

Explanation:

Mendel's first experiment was a monohybrid cross. He took true - breeding pea plants with contrasting traits (e.g., tall vs. short). He cross - pollinated a true - breeding tall pea plant with a true - breeding short pea plant. The offspring (F₁ generation) were all tall. Then he allowed the F₁ generation to self - pollinate. In the F₂ generation, the ratio of tall to short plants was approximately 3:1. This experiment helped him formulate the law of segregation.

Answer:

Mendel's first experiment was a monohybrid cross. He cross - pollinated true - breeding pea plants with contrasting traits (e.g., tall and short). The F₁ generation was all tall. F₁ self - pollination gave an F₂ generation with a ~ 3:1 (tall:short) ratio, leading to the law of segregation.
