Document Summary
Seed shape in pea plants) was directed by factors inside organisms. A trait with two contrasting forms (ex. Round or wrinkled peas) was directed by two different factors that behave independently. Gamete cells (such as pollen grains and egg) contain only one of these two factors. A particular factor would be expected to be found in half of the gametes. Fertilization requires the fusion of two gametes and is random. The advantages of using pea plants for genetics. Easy to grow and short generation time. Available in many varieties with distinct heritable features (characters) with different variants (traits) Each pea plant has male (stamens) organs and female (carpal) sexual organs. The anther contains the pollen grains where the male gametes are produced. In nature, self-pollinate, fertilizing ova with their own sperm. Moved pollen from one plant to another by hand. Transferred pollen from the anther of plant to the stigma of another plant.
