Mendel chose garden pea (Pisum sativum) as plant material for his experiments, since it had following advantages: 1. Module 5 DQ 2 The power of inheritance of traits. An example of a Retrovirus is HIV (Human Immunodeficiency Virus). In actuality now that the pea genome is sequenced the location of Mendel's 7 traits are documented and they are not one per chromosome. They also have several visible characteristics that vary. 1) Because they are easy to grow 2) They have many traits that distinguishes strains of peas 3)Their traits can be tracked from one generation to the next Peas have characteristics that have two forms. This Gregor Johann Mendel was a scientist, meteorologist, mathematician, biologist, Augustinian friar and abbot of St. Thomas' Abbey in Brno, Margraviate of Moravia. Gregor Mendel crossed homozygous tall plants (TT) with homozygous short plants (tt). They Produce sexually Which describes the mating of organisms that have different homozygous alleles for a single trait? This indicates how strong in your memory this concept is. If a child has freckles, at least one parent has freckles. An acquired trait is developed during one's lifetime. Its flowers were hermaphrodite, which means, pea plant has both male and female sexual organs.
