Detailed explanation-1: -Mendel showed that when two varieties of purebred plants cross-breed, the offspring resembled one or other of the parents, not a blend of the two. He found that some traits are dominant and would always be expressed in a first generation cross, while others are recessive and would not appear in this generation.
Detailed explanation-2: -Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent.
Detailed explanation-3: -These plants would serve as the P1 generation for the experiment. In this case, Mendel crossed the plants with wrinkled and yellow seeds (rrYY) with plants with round, green seeds (RRyy). From his earlier monohybrid crosses, Mendel knew which traits were dominant: round and yellow.
Detailed explanation-4: -Dominant and recessive traits 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.
