Document Summary
What are the advantages/disadvantages of sexual reproduction vs. asexual reproduction: unique characteristics (beautiful, flowers, bird songs, smell) are the products of sexual selection. Sexual reproduction places different selective pressures on males than females: sexual reproduction new alleles) Produce new combinations of alleles (mutation produces. Male: many small gametes female: few large energy rich immobile gametes. Allows genetic recombination to happen: asexual reproduction gives less genetic variation, gives rise to genetically identical individuals. Why would asexual creatures need to copulate to reproduce: if they have evolved from a recent common ancestor that reproduced sexually. Sex, recombination, genetic diversity reproducing sexually generates new combinations of alleles. Bacteria reproduce through binary fission, but not sexually, this is asexual. Can have the transfer of genetic info that doesn"t result in reproduction. Bacteria transfer genes often: strengthens antibiotic resistance, recombination can happen, however this can be the transfer of, every individual is born female, cannot reproduce sexually, must genes, not sexual reproduction.
