Detailed explanation-1: -Mendel crossed pure lines of pea plants. Dominant traits, like purple flower colour, appeared in the first-generation hybrids (F1), whereas recessive traits, like white flower colour, were masked. However, recessive traits reappeared in second-generation (F2) pea plants in a ratio of 3:1 (dominant to recessive).
Detailed explanation-2: -Gregor Mendel experimented with pea plants to learn how characteristics are passed from parents to offspring. Mendel controlled pollination in pea plants in order to research how characteristics are passed from parents to offspring.
Detailed explanation-3: -By experimenting with pea plant breeding, Mendel developed three principles of inheritance that described the transmission of genetic traits, before anyone knew genes existed.
Detailed explanation-4: -Mendel proposed three laws: Law of Dominance. The Law of Segregation. Law of independent assortment.
