What evolutionary advantage is provided by sexual reproduction?

Question

Is it:

1. increased genetic diversity
2. making clones
3. making diploidy possible
4. being able to work with chromosomes

I think it is 3, but not sure.

Answer 1

Increased genetic diversity. Asexual reproduction, ie budding from the parent body, relies upon random genetic mutation in order to achieve diversity. Sexual reproduction blends genes from two sources in order to create a new individual quite different from the two parents. It is this blending which creates diversity.

Answer 2

Sexual reproduction provides vast potential for genetic recombination, thus expediently faciltating evolutionary processes. Asexual reproduction only produces offspring with the same genes as the parent, essentially making offspring identical genetic clones. In a stable environment where the organism is well adapted, this strategy is fine. However, in a dynamic environment where pressure to adapt is great, sexual reproduction provides more options for evolutionary advancement. Therefore, it is truly the nature of the environment that dictates whether or not sexual reproduction is an advantage--it may also be an unnesseccary use of energy resources in stable environments.

Answer 3

It's 1 and 3. By reproducing sexually organisms take half the genetic information from one parent and half from the other to make a new completely different offspring. This offspring will have characteristics randomly from each parent. Some will offer it an advantage over the parents, and some will offer it a disadvantage.

Thus the offspring may have a better chance of survival in different and changing environments over their parents.

With asexual reproduction, the offspring is exactly the same as the parent. This offers a benefit when the organisms and their offspring will be living in an environment that does not change. They offspring will have the same chance of survival as it's parent.

Answer 4

The most correct answer is 1. Sexual reproduction increases the chances of variation within a species.

Answer 5

The answer is #1 because sexual reproduction leads to haploids, not diploids, it does not makes clones aka genetic duplicates, and chromosomes are present in both meiosis and mitosis. Sexual Reproduction, however, does lead to genetic diveristy by allowing the recombination of genetic traits.

Answer 6

All sexual reproduction does is keep the specie going. We can't measure any evolution, unless we live a million years or more. Don't worry about evolution beyond today. None of us will be here to notice any difference.

Answer 7

sexual reproduction leads to the genetic variability due to which the new off-springs r more comfortable and well-adapted to the envoironment as compared 2 their parents coz their genome is modified.so i think,its # 1

Answer 8

1, diversity is the biggest advantage of sexual reproduction

Answer 9

1
sexual reproduction provides genetic charactaristics of both parents creating offspring that aren't geneticlly the same as the parents.

Answer 10

INCREASED GENTIC DIVERSITY!!!!!!!!!!!!!!!!!!!!!
