WebSection Summary. Working with garden pea plants, Mendel found that crosses between parents that differed for one trait produced F 1 offspring that all expressed one parent’s traits. The traits that were visible in the F 1 generation are referred to as dominant, and traits that disappear in the F 1 generation are described as recessive.

WebMendel experimented on a pea plant and considered 7 main contrasting traits in the plants. Then, he conducted both experiments to determine the inheritance laws. A brief explanation of the two experiments is given below. Monohybrid Cross. In this experiment, Mendel took two pea plants of opposite traits (one short and one tall) and crossed them. WebMonohybrid crosses: The F2 Generation . Next, Mendel took the F1 progeny and allowed them to self-fertilize. In the resulting F2 generation, 3/4 showed the dominant phenotype, and 1/4 showed the recessive phenotype. For example, when a round seed line was crossed to a wrinkled seed line, the F1 generation was all round, and the F2 generation … WebMendel then crossed these pure-breeding lines of plants and recorded the traits of the hybrid progeny.
