Inheritance And Natural Selection On Survival Of Beetle Race

Exercise 1a reproduced the outcome of 30 beetle population size that has a ratio of 1:1:1 in red, orange and yellow phenotypes and indistinguishable predation ratio (1:1:1) over 20 generations. 3 trials out of 4 showed an analogous trend, the highest frequency of alleles is the yellow phenotype after the 14th generation in trial 2 and 3 and 13th generation in trial 4, making the overall surviving beetle population by 20 generations. The red beetle population showed a drastic extinction after the 13th generation in the first trial, 14th generation in second trial and 10th generation in third trial. However, the orange beetle coloration is at all times unbeaten at the beginning of the experiment, exceeding the survival of yellow beetles up to 18th generation in second trial (figure b), 14th generation in third trial(figure c) and 12th generation in fourth trial(figure d). Trial 1 showed a different trend where
