Why is sexual reproduction considered better from an evolutionary standpoint?
Wiki User
∙ 12y ago
Sexual reproduction, as opposed to asexual reproduction, combines the genomes of two different individuals to create a new genome in the offspring. This new genome has the potential to include the beneficial (or detrimental) alleles (genes) from each individual, thus driving evolution. An individual which reproduces by asexual reproduction is restricted to evolution by mutation (or complicated mechanisms such as horizontal gene transfer but that's a much bigger issue). Mutation can be good or bad, either helping the organism adapt to the environment or worsening its ability to survive and reproduce, an asexual organism is stuck with the mutations it acquires. Sexually reproducing individuals can have mutations as well, but then those mutations that the offspring acquire may be balanced out, i.e. beneficial mutations are selected for, detrimental ones are selected against and then individuals with different beneficial mutations can bring such advantages together in their offspring.
Put simply, sexual reproduction increases the evolvability of an organism.

What is the meaning for adaptive traits of reproduction?
A reproductive adaption is considered be a peculiarity of the reproductive mechanism within a species. This results in the species, whether plant or animal, to fit in better within its environment.
Why are seeds considered a more effective means of reproduction than spores in a dry environment?
because seeds can store food and nutrients when spores cant, so seeds have a better advantage of surviving in a dry environment.
What is adaptation in biology?
In bio, adaptation usually refers to an evolutionary change an organism has made to better suit its environment. This change is a process and usually takes thousands of years. Evolutionary adaptation is not to be confused with acclimation, which is when an organism simply gets used to its environment during its lifetime and makes no evolutionary changes.
How do scientists determine the evolutionary relationship among species?
They use a taxonomic map to help classify organisms. The placement of organisms on this was originally based on similarities between species. Today we are able to look at their actual genes, which has resulted in a better understanding of evolutionary relationships - or the lack of them- and has resulted in some re-classification.
Which is better mode of reproduction sexual or asexual and why?
Asexual reproduction is favourable if horizontal gene transfer can make up for the lack of diversity within species. Horizontal gene transfer is when two mature organisms can switch or share different genes. (Many bacteria and archea can do this) Horizontal gene transfer is quite difficult for multi-cellular organisms, so sexual reproduction is preferable. The goal of reproduction is to create offspring that will survive in changing environment - so there must be a mechanism to create many different kinds of offspring. Sexual reproduction affords this. However - the optimal form of reproduction is to have the choice to reproduce either asexually and sexually. If there is a disaster (for humans) or a new antibiotic (for bacteria) it may be preferable to reproduce asexually for a while if no other similar species are around. Later, when the population is big enough, sexual reproduction can begin to recover genetic diversity. (I am assuming that clones don't reproduce with themselves the whole time). This may be the new and improved 'bisexual' of the future.
What are the evolutionary advantages achieved by the myelinatio of neurons?
Myelin allows for much faster conduction speeds. Faster is better in evolutionary terms.
What is the effect differential reproduction overtime?
Differential reproduction refers to the process where individuals with certain traits are more likely to survive and reproduce than others. Over time, this can lead to the accumulation of advantageous traits in a population through natural selection, driving evolutionary change. This can result in adaptations that are better suited to the environment, increasing the overall fitness of the population.
How is reproduction managed?
loosely. The looser the better...
Is it good or bad to fart?
From a health standpoint, it's better to let it out than hold it in.
What is the meaning for adaptive traits of reproduction?
A reproductive adaption is considered be a peculiarity of the reproductive mechanism within a species. This results in the species, whether plant or animal, to fit in better within its environment.
Why is it better to reproduce sexually?
It is better because then you get diversity. DNA is passed down in any reproduction, but while asexual reproduction is basically cloning from one parent, as in bacteria, sexual reproduction passes down DNA from two parents, each with their own unique DNA, which leads to diversity.
What are the conditions of natural confitions?
Natural selection is a process by which organisms that are better adapted to their environment tend to survive and reproduce more successfully, leading to evolutionary changes in populations over time. It results from variation in traits among individuals, heritability of those traits, and differential survival and reproduction based on those traits.
Why are seeds considered a more effective means of reproduction than spores in a dry environment?
because seeds can store food and nutrients when spores cant, so seeds have a better advantage of surviving in a dry environment.
Can an 8086 processor be used in embedded systems?
Yes, although the 80188/80186 would be a better choice from an integration and simplicity standpoint.
What is a sentence with Sexual reproduction in it?
sexual reproduction leads to genetic variations in the progeny. It helps to create organisms with better adaptability to the prevailing environmental conditions.
Advantage of sexual reproduction?
Despite the obvious efficiencies of many forms of asexual reproduction, sexual reproduction abounds. Asexual species, for the most part, are relatively short-lived offshoots of sexual ancestors. From the nineteenth century, it has been recognized that, since there is no obvious advantage to the individuals involved, the advantages of sexual reproduction must be evolutionary. Furthermore, the advantage must be substantial; for example, producing males entails a two-fold cost, compared to dispensing with them and reproducing by parenthetic females.sexual reproduction offers the opportunity to produce recombinant types that can make the population better and able to keep up with changes in the environment. And Sexual feels so great. You don't even know.
Why do angiopsperms outnumber gymnosperms?
Because they are better adapted for reproduction and dispersal of their seeds.
