Some advantages of sexual reproduction are that genes vary between generations. Also, changing genes can get rid of harmful mutations that the parents may have accumulated in their genes according to Muller's theory. When their are offspring that have many harmful mutations, those mutations will not be passed on and will end there. A disadvantage to sexual reproduction, as claimed by Dr. Tatiana is that there is competition between males and that qualities that attract a mate may not be the same qualities needed to survive.
An advantage to asexual reproduction is that to keep the population the same, each female needs to have one offspring, as supposed to two in sexual reproduction. Also, asexual organisms have been living on earth the longest according to Miss Philodina. A disadvantage to asexual reproduction is the susceptibility to diseases. The red queen theory points out that if one asexual organism is susceptible to a certain disease, than the entire population can be wiped out by a single disease.
Something I would like to know is why some species reproduce asexually and others sexually.
