Let say, for example, if palm seeds which are larger have high fitness than the palm seeds which are smaller then we will say that the fitness of palm will decrease over time when toucans are absent. This is because the large seeds will have a lower chance of survival and they will not be dispersed. Largest palm seeds where some are the size of marbles inside a thin-skinned fruit which is too big for most birds especially for toucans which have a big mouth. If toucans disappear the palms which need big seeds have a good luck because of no seed dispersers. Some trees like jucara which are genetically predisposed and make small seeds have started to dominate the forest and thrive.
Crossing over increases genetic variation because due to this, each of the homologous chromosomes get a new combination of traits/ genes and since a each cell has different homologous chromosomes, genetic variotion will occur
