Answer :
Self pollination occurs before the flowers open, so progeny are produced from a single plant.
He chose peas because they had been used for similar studies, are easy to grow, and can be grown every year. Pea flowers contain male and female parts, called the stamen and stigma, and are usually selfpollinating. To do so, he first established lines of peas with two different forms of a feature, such as tall vs short height.He bred these lines for generations until they were pure and always produced offspring identical to the parents, then crossed them with each other and watched as the traits were inherited. Mendel studied seven characters of the pea plant in his experiments.The characters chosen by Mendel were seed color, seed shape, stem height, flower color, flower position, pod color, and pod shape. He showed that traits are faithfully passed from parent to offspring in specific patterns.
