BIOL 1107 Lecture Notes - Lecture 99: Gamete, Reciprocal Cross, Gregor Mendel
Document Summary
Genetics is the branch of biology that focuses on inheritance. Gregor mendel was: a 19th-century monk, active member of his city"s agricultural society, mendel was interested in heredity. Heredity: the transmission of traits from parents to their offspring. What question was mendel trying to answer: mendel was addressing the basic questions, why offspring resemble their parents, how transmission of traits occurs. In his time, two hypotheses had been formulated to try to answer this question: blending inheritance. Such that their offspring have intermediate traits: inheritance of acquired characteristics. Genetics: the branch of biology that focuses on the inheritance of traits, uses model organisms, because the conclusions drawn from them can be applied to other species. How did mendel arrange matings: peas normally pollinate themselves. Bio 1107. 020 (3-5-2014: mendel could prevent self-pollination by, removing the male reproductive organs containing pollen from each flower, he then used this pollen to fertilize the female reproductive organs of flowers on different plants.
