Document Summary
10. 1 the beginnings of genetics: mendel"s garden peas. Until 1900, blending theory of inheritance was believed suggests that hereditary traits blend evenly in offspring through mixing of parent"s blood. In his work with peas, mendel studied heritable characteristics called characters (ie. flower colour or seed shape) Mendel established that characters are passed to offspring in the form of discrete hereditary factors, which are now known as genes. Found that many traits either appeared in offspring or disappeared. Inheritance patterns he observed are the result of the segregation of chromosomes, on which the genes are located, to gametes in meiosis. 10. 1 a mendel chose true-breeding garden peas for his experiments. Chose garden peas because the plant could be grown easily in monastery garden. Flowering plant: male gametes are sperm nuclei in pollen (produced in anthers of the flower) & female gametes are egg cells (produced in the carpel of the flower)
