Is Crossover a form of mutation? - Crossover Mutation (Nov/06/2008 )

I have been interest in the Crossover process in sexual reproducing organisms.
and weather the phenotypic diversity expressed is actually a form of Mutation?
When an organism develops a haploid sex cell from a diploid cell, it only contains half the chromosomes. As each parent of the haploid cell have different genes, and the selection of these genes is supposedly random as each allele will not match base pair to base pair from each parent, is this a form of mutation? or is there some algorith to the diversity created by sexual reproduction?
If not, why not?

Good question, I´d say that this is a very separate phenomenon from mutation. It is arguable whether you could sayt that recombination creates diversity. Within the individual, yes, because you get two different copies of your genes, some pairs being different. But at the population level, recombination is actually a homogenising phenomenon. By exchaning genetic material, the population is kept from diverging.
