From the classroom to an opinion note: complementary analysis of the genetic structure of the neotropical tree manilkara zapota (L) P. Royen (Sapotaceae)

Abstract

Here, we describe a learning strategy that results an excellent choice for a first approach of students to produce scientific knowledge that can be confronted in the scientific field as well as recognize in this knowledge the transferability to the natural resources management. Nowadays, the availability of several Population Genetics software together with public molecular database represents a valuable tool of great assistance for teachers of this discipline. In this way, we implemented a lecture where the students worked with empirical data set from a recent published article. The students joined theoretical concepts learned, computational software free available and empirical data set. The development of the activity comprised four steps: i) estimate population genetics parameters using software recommended by teachers, ii) understand results in a biological sense, iii) read the original manuscript from dataset authors and iv) compare both results in a comprehensive way. The students assumed the challenge under a reflective look and they kept a very fruitful discussion playing a role of population geneticists. Their exchange of ideas allowed them arrive to the conclusion that Manilkara zapota populations keep high levels of genetic diversity, although Ancient Maya left traces in the genetic makeup of these non-native populations with different management histories.
