Document Summary
Offspring are not necessarily identical in phenotype to parents, and could get a maladaptive phenotype because of diversity in the offspring. Meiotic cost of sex: parent only determines half the genetic makeup of their offspring, the other half is dependent on the mate. Implications of non-random mating on individual genotypes and population compositions. Energy-intensive: lack of attention of predators, finding food, etc. Produces a diversity of offspring the lottery model. Increased probability of some offspring surviving/having favourable phenotypes. When organisms asexually reproduce all the offspring are identical to the parents. When organisms sexually reproduce each offspring has unique variations some of these variations may be advantages or disadvantages. By having diversity in the offspring there is a greater probability that at least one of the offspring"s phenotypes will be successful.
