Pollination is vital for the lifecycle of flowering plants because they are physically unable to mate. When animals or insects carry pollen from one plant to another, they help the plant sexually reproduce by bringing sperm producing cells (pollen) and eggs together. What are the most common pol...
Plant reproduction is the process by which plants generate new individuals, or offspring. Reproduction is either sexual or asexual. Sexual reproduction is the formation of offspring by the fusion ofgametes. Asexual reproduction is the formation of offspring without the fusion of gametes. Sexual reprodu...
Pollination is essential to the perpetuation of the vast majority of the world’s wild plants—and thus the perpetuation of nearly all terrestrial ecosystems—as well as to the production of most of the fruit and seed crops that feed humanity. The importance of this seemingly simple movement of...
Flowers that are designed to be fertilized by bees won't be able to accommodate the long beak of a hummingbird and thus cross-pollination between these species will not occur.Mechanical Isolation vs. Other Types of Isolation Lesson Summary Register to view this lesson Are you a student or a...
When we discuss sexual reproduction in plants, we come across 3 major ways that it could possibly happen;“allogamy”, “autogamy”and “geitonogamy”. Allogamy Allogamyis the“cross-pollination phenomenon”where pollen’s spermatozoa from a plant’s flower fertilize the ovum of a different...
A pollen grain is a small collection of microspores that aid in fertilization and sexual reproduction in plants. It is attached to the anther of the male reproductive organ of the plant. Through self-pollination or by cross-polination through the assistance of pollinators, the pollen grains are...
Gregor Mendel is credited as the father of modern genetics. He was the first to discover that the patterns of the passage of traits from parents to offspring could be predicted. Mendel studied the inheritance of traits in pea plants from true-breeding plants. True-breeding refers ...
Composite cross populations are formed by assembling seed stocks with diverse evolutionary origins and characteristics, recombination of these stocks by cross pollination, the bulking of F1 progenies, and subsequent propagation of the bulked progenies in successive natural cropping environments. Natural ...

After completing his university studies, Mendel decided to conduct experiments in the cross-pollination of garden peas. For his studies, Mendel picked seven specific traits: Pea color (green vs yellow) Seed shape (smooth vs wrinkled) Flower color (white vs purple) Pod color (green vs yellow) ...
