Tuesday 26 June Variation SLO: Recall how characteristics are inherited describe how variations occur. Discussion – are we all the same, in what ways are we different, why are individuals in populations different (as opposed to populations that are all the same eg monocultures – variation gives us a greater chance of having some individuals survive if there are adverse conditions eg drought, disease), how do these differences (variation) occur and in what type of populations (in sexually produced populations as opposed to asexually produced populations. Variations arise due to combining the gametes (sex cells), amongst other things (we’ll get into those specifics a little later on). Variation in Class experiment – measure heights of class (using the 1m rulers, work in pairs and measure each others heights). Record on whiteboard in cm (names not necessary). Do a talley eg 150-159cm – 5, 160-169cm – 8 (start from the lowest heights working up to the tallest, tallying up how many in the class fit into each). Graph results and compare to bell-shaped curve (normal distribution curve). What other human characteristics could be graph to get a bell-shaped curve? (eg weight) Notes for variation into books: Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits flexibility and survival of a population in the face of changing environmental circumstances. Consequently, genetic variation is often considered an advantage, as it is a form of preparation for the unexpected.
