Document Summary
Blending theory hereditary traits blend evenly in offspring through mixing of parents" blood. Mendel studied characters heritable characteristics (ex. flower colour + seed shape) Genes - characters are passed to offspring in form of discrete hereditary factors. Observed that many parental traits appear unchanged in offspring, whereas other disappear in one generation to reappear unchanged in next: mendel chose true-breeding garden peas for his experiments. Male gametes = sperm nuclei, contained in pollen, produced in anthers of flower. Female gametes = egg cells, produced in carpel of flower. Pea plants self-fertilize or self-pollinate sperm nuclei in pollen fertilizes egg in carpel of same flower (however, mendel cut off the anthers, preventing self-fertilization, so pollen came from different plant) Chose plants that were known to be true-breeding / pure breeding passed traits w/o change from 1 generation to next: mendel 1st worked w/ single character cross.
