What can cause variation within a species?
Reproduction produces variation in population gene pools. Every time organisms reproduce, be this sexually or asexually, the genome of the offspring is slightly offset compared to that of its parent(s). Additional factors in this may be mutagenic influences in the environment, such as radiation.
Why genetic variation is of to benefit to a population?
It can provide resistance to diseases or other beneficial characteristics. -variation in more competitive species than our own can result in natural selection that is better focused to the specific environment: there is a bigger range of characteristics, so the best traits allow those members to survive longer and therefore mate more. This allows the species overall to constantly reproduce the beneficial traits and flourish.
Why do some organisms reproduce both asexually and sexually?
The strategy increases chances of survival for that species.
Do protozoan reproduce sexually or asexually?
Roundworms reproduces sexually ... .. the female has an ovary, holds eggs in the oviduct that then move to the uterus, where they are fertilized as normal. The male has sperm cells are made conventionaly in the testis as in other spieces that reproduce sexualy.
Why could natural selection not occur without genetic variation in a species?
Natural selection is a change in allele frequencies of a species which allows that species to better survive in it's environment. Without genetic variation there would be no change in the allele frequency of a species. However, with genetic variation there is a chance that one particular member of a species will be born with a random mutation which allows it to better survive in it's environment, thus increasing the chance that it will reproduce and pass on that genetic trait to it's offspring who in turn will pass it onto their offspring and so on. Without genetic variation all members of the species and their offspring would be exact duplicates of each other and no particular member would have an advantage over another.
Do protozoa sexual or asexual?
Most protozoan species can reproduce both asexually and sexually!!!
Do penguins reproduce sexually or asexually?
Like all birds, fish and mammals - they produce sexually. They need a male & a female to reproduce the species.
What does the sexual reproduction give the species?
Species that reproduce sexually can evolve more rapidly than species that reproduce asexually.
Do snakes reproduce by fragmentation?
Snakes can not reproduce by fragmentation. Snakes reproduce sexually. Some species of snakes, such as the Copperhead, can reproduce asexually.
What allows variation among a species that reproduces sexually?
The combination of genes
When is a species extinct?
Hi A species becomes extinct when the last existing member of that species dies. Extinction therefore becomes a certainty when there are no surviving individuals that are able to reproduce and create a new generation. A species may become functionally extinct when only a handful of individuals survive, which are unable to reproduce due to poor health, age, sparse distribution over a large range, a lack of individuals of both sexes (in sexually reproducing species), or other reasons.
What would happen if all individuals in a species?
If individuals in a species never reproduce ,it would mean an end to that species on earth
Are praying mantis asexual?
No, they reproduce sexually. Some of the species praying mantis can be reproduce asexually. But not all the species of praying mantis asexual.
Does a DOLPIHN reproduce sexually or a sexually?
All mammals reproduce sexually. In fact, the dolphin is one of the few species that have sex just for pleasure's sake, with both male and female pod members.
Do birds reproduce sexually or asexually?
Birds reproduce sexually.Bird species all reproduce sexually. It takes a male sperm to fertizile the female egg that is laid and will hatch into a chick.
How can variation occur in species that dont reproduce sexually?
Randomly and naturally occuring mutation. A virus might also inject some DNA into their spores or something as well.Bacteria take in DNA fragments from their environments.
