Define the following terms related to alterations of generations:
a.Haploid
b.Diploid
Most eukaryotic organisms use sexual reproduction as their primary means of perpetuating their species. Gametes are formed via meiosis. However, some species primarily reproduce via asexual means. Reproduction is accomplished via mitosis. Aspen trees most commonly reproduce by such asexual methods of cloning.What are the advantages and disadvantages of reproduction by asexual means?
Why do some species reproduce in this manner?
Why don't all species?
