Why is sexual reproduction more evolutionarily advantageous than asexual reproduction?

Answer 1

it has is advantages and disadvantages both are just as important. Sexual reproduction requires a lot of time and energy, mate selection, gamete production and housing a developing embryo are a few reasons for this. However, sexual reproduction leads to a stronger mix of genes which allows a stronger species to evolve. It also gives rise to more complex organisms.

Answer 2

Asexual reproduction is cloning ... just copying the exact same data present in the parent. There is no genetic recombination allowed in this format, unlike sexual reproduction. How often do you get a completely different image from a perfectly operating xerox machine photographing the same page from a book?

Sexual reproduction sacrifices half of the genetic information, but allows for recombination with a different set of DNA codes. This allows for a higher level of genetic diversity. With two unique sets of genetic information, the offspring will be the result of the two successful gametes that fertilized to develop into it.

Answer 3

Sexual reproduction is most advantageous , due to genetic variation .
Meiosis plays an important part in sexual reproduction.
During meioisis , after synapsis , genetic recombination occurs , dure to which we get varied gene pairs as well parental strands too .
Nothing like that happens in Asexual reproduction .The offsprings are just exact copies of their parents .
Due variations in sexual reprodcution , the offsprings have more chances of survival in difficult conditions , they can cope with and adapt in various condtions .
Where asexually reproduced organisms , cannot adapt to various condition s, they can also have less immunity for diseases !
Hope this helps you!

Answer 4

The only reason I could think of would be that we can't produce too quickly to outgrow our environment that way. As you know if a life form reproduces too quickly, the results for it's species could be potentially distasterous. But I'm sure there are probably a few more reasons. I haven't studied that area enough to give them to you though.

Edit: Duh, I forgot about DNA. I'm a twit today. We do need variation, which well, asexual reproduction doesn't really offer like sexual reproduction. Variations are absolutely necessary for evolution of course.

Answer 5

Sexual reproduction is important for the production of genetic variation, while this is not possible with asexual reproduction.

Answer 6

the genetic variation and randomness created through sexual reproduction allows it so that if something affected one individual it wouldnt affect the rest...

it also allows for more improvement, by natural selection and mate selection so better genes get passed on... ensuring a stronger progeny better suited to survive and flourish.

with asexual reproduction everything usually stays the same and nothing changes... if something were to happen entire colonies could die out... rather than a few susceptable individuals...

Answer 7

sexual reproduction has the ability to combine the genetics and traits of the 2 mates, asexual reproduction in essence reuses the same DNA over and over again. this wears down the celluar structure of the organism, over many generations.

Answer 8

sexual reproduction involves variation unlike asexual reproduction. the more uniform or similar a certain species are the more likely it is swept away by some kind of disease.

Answer 9

while an organism in user-friendly terms makes use of asexual reproduction, all its offspring are comparable (different than for the uncommon mutations that ensue). that's no longer sturdy for all times in a changing environment full of opposition for scarce materials. truly, sexual reproduction potential that the offspring are no longer precisely like the mothers and fathers. remember that meiosis consists of crossing over of homologous chromosomes (prophase), self sufficient number of chromosomes so as that each and each gamete (egg or sperm cellular) incorporates most of the maternal and a great sort of of the paternal DNA, and then the act of fertilization that leads to a diverse offspring.

Answer 10

it isnt................ sexual reproduction is far LESS advantageous and usually results in unhappy abusive families... poverty, unwanted children that are also abused etc etc............... they grow up to do the same and its just dumb.
asexual reproduction ensures adequate care for the child.
sexual reproduction promises nothing........... low quality people even choose for themselves low quality mates..........resulting in a continuing low quality lifestyle that is like a blood sucking parasite to the planet........... costing billions of dollars and still not making a dent in fixing the problem , but yet bringing the rest of us down with them. duh. its quite clear and I hope thats what you were getting at
