Studying Trait Inheritance Through Observing Brassica Rapa Diego Herrera Introduction Gregor Mendel first studied patterns of trait inheritance in the 1800’s. Mendel performed experiments on pea plants that tracked the passage of traits from generation to generation. Through his research he formulated the law of segregation it stated that allele pairs separate during the formation of gametes, with the paired condition being restored during fertilization to form a zygote (Morgan & Carter 2011). Mendel’s research did not become recognized until the 20 th century but his research was found to be very useful in the field of genetics because it allowed scientists to formulate testable models from which they could hypothesize. At first Mendel’s results were controversial because it went against what was thought to be true at the time that traits blended together, but Mendel proved blending to be false when his research showed that alleles are particles that don’t blend. In this lab the plant Brassica Rapa will be used to study the inheritance of traits. Brassica Rapa, also know as “Wisconsin fast plants”, is an ideal species to study inheritance because the entire life cycle of a fast plant is 35 days, this is a good attribute for a studied species to have because the generational turn around time is short so passed on traits can be viewed quicker. Another characteristic that makes Brassica Rapa an ideal species is that they are small and don’t take up a lot of space so more of them could be
