Document Summary
What are the basic patterns in the transmission of traits from parents to offspring: hi: blending inheritance o, concept of blending of inherited traits once trait is blended" can"t get the original types back. Gregor mendel: heredity: the transmission of traits from parents to offspring, question: why offspring resemble their parents and how transmission of traits occurs, studied heredity in a scientific way, particulate hypothesis of inheritance, terminology: Self-pollination: pollen from stamen fertilizes egg in carpel of same flower. Cross pollination: fertilization of one plant by pollen from another plant. Genotype: the alleles found in an individual. Homozygous: an organism with identical alleles for a character. Heterozygous: an organism with different alleles for a character. True-breeding: individuals that produce offspring like themselves over many generations of self-pollination. Hybridization: created by mating two true-breeding varieties: p parental generation (true-breeding parents, f1 first generation, f2 second generation. Mendel studied seven characters that were variable in pea plants.
