Dominant traits, like ‘T’ in this example, are expressed even if only one copy of the gene is present. Recessive traits, like ‘t’, are expressed only when both copies of the gene are recessive

Mendel concluded that both the tallness and shortness traits were inherited in the F1 plants, but only the tallness trait was expressed in the F1 generation. The appearance of short plants in the F2 generation indicated that the shortness trait ...

Mendel conducted self-pollination experiments with both the parental plants and the F1 tall plants. When the F1 tall plants were allowed to reproduce through self-pollination, the resulting second-generation, or F2, progeny exhibited a mix of tall and short plants. This ...

In the F1 progeny resulting from the cross of pea plants with different characteristics, Mendel observed that there were no halfway characteristics. For example, if a tall plant and a short plant were crossed, all plants in the F1 generation ...

Mendel used contrasting visible characters such as round/wrinkled seeds, tall/short plants, and white/violet flowers in his experiments with garden peas. These characters were important as they allowed him to observe and analyze the inheritance patterns of specific traits, providing clear ...
