What circumstances that genetic drift occur?
Genetic drift is the fluctuation of allele frequencies in a population due to chance. Chance plays a role in several ways. Copies of alleles can be lost because they never make it into gametes. Another possibility is, if the allele copy makes into a sperm, that sperm isn't the one that fertilizes an egg. Maybe the organism that carries copies of the allele in its gametes fails to find a mate, or is killed before reproducing. These kinds of events can influence the frequency of that alelle in a population, and occurs regardless of any selection for or against that allele. Obviously, the smaller the population, the larger the effect drift has on the allele frequency. For example, consider a population of four organisms. Each has two copies of a particular gene (one on each chromosome). Now, consider a mutation that creates a new allele for that gene, and that it appears on one chromosome of one individual. That allele will have a frequency of 1/8 in that population, so if it is lost, the frequency change will be 1/8. Now imagine a population of eight individuals; the frequency of the new allele would be 1/16, so if it was lost, the change in frequency would be less than in a population of four. It should therefore be easy to see that the effect of genetic drift on allelic frequency change is dramatically less in very large populations. In fact, in an essentially infinite population, genetic drift would have a negligible effect on the frequency of an allele. Another factor that can influence allele frequency, and which is a part of genetic drift is non-random mating. If an organism does not have an equal probability of mating with any other organism in a population, then some alleles will increase or decrease in frequency simply due to that. For instance, if a population exists over a large geographic range, individuals that live closer to each other have a greater probability of mating than those who live far apart. Species who employ reproductive strategies such as leks,where males gather together and compete for the privilege of mating with females are also examples of non-random mating. Lekking increases the effects of drift because it reduces what biologists call the effective population size, or the number of breeding adults. For the above reasons, when population geneticists want to study factors that affect the frequency of an allele (such as natural selection), and they want to minimize the effects of drift, they model populations that are very large (essentially infinite) and assume random mating.
What does fitness relate to Darwin's theory?
Fitness is generally measured in average number of fertile offspring.
How can you get answers for your science book you live in NC using the 7th grade science book its yellow with fish on the front?
There usually a website for the book, or some of the answers could be in the back.
How does natural selection work in the environment?
Some individual organisms are better equipped to live and reproduce in their environment than others. If what makes them better equipped is heritable, their offspring will be more numerous and will tend to inherit the same traits or qualities themselves. The opposite will happen to those poorly equipped. They will have fewer or no offspring, and their negative traits will tend to disappear from the population as time goes on. These two tendencies are called positive (natural) selection and negative (natural) selection respectively. Natural selection is always relative to the environment. What is advantageous in one environment may not be so in another, and what is disadvantageous (deleterious) in one environment may not be so in another.
What are 3 principals of gentics?
six basic principles of genetics are....Traits, or characteristics, are passed on from one generation of organisms to the next generationThe traits of an organism are controlled by genesOrganisms inherit genes in pairs, one gene from each parentSome genes are dominant, whereas other genes are recessiveDominant genes hide recessive genes when both are inherited by an organismSome genes are neither dominant nor recessive. These genes show incomplete dominancesource: i got this from my textbook.....and im in 7th grade. the txtbook is called Prentice Hall Exploring Life Science
Why is it important for an offspring to inherit the traits from its parents?
Offspring must inherit traits from its parents because it parents contained genes that were dominant and survived. the genes passed from parent to offspring are important because they are the dominant genes of survival. they passed of survival genes to help their offspring live longer.
Why are dominant alleles that cause lethal disorders less common that recessive alleles that cause lethal disorders?
A lethal dominant gene prohibits the organism from reproducing irregardless of the paired gene, so it is removed from the gene pool as soon as it appears. A lethal recessive gene, on the other hand, does not prevent reproduction unless it is paired with another lethal recessive, so it may be passed down through many generations before becoming paired and preventing reproduction.
Is the white tigers fur mutation dominant or benificial?
Well, the white tigers fur mutation isn't dominant nor beneficial (depends). The allele for white fur in tigers is recessive and even then not many tigers are heterozygous (One dominant allele and one recessive allele for those who do not know) Now it can be beneficial depending where the tigers live, there used to be Siberian Tigers who lived in the snow so it would be beneficial there but white fur will decrease stealth ability in the jungles, therefore alleles can be beneficial or harmful depending on the allele and where the organism lives.
Does a pig give birth to live offspring?
Yes, because they are mammals, and all mammals give birth to live offspring.
A sentence for dominate?
there are many Dominant facts. Live a dominant life.
Why is selective breeding a slow process?
because when you take a gene from another species they don't always turn out the way you whant them to for example; if you take a gene from a blue plant and put it into a red plant you might get a verious of colour because somewhere in the family tree there would be a different colour of parents.
How do guinea pigs live in the wild?
They live in herds of about ten, more or less, members. There is usually a dominant male and dominant female. They live in burrows. Often members of a herd fight to establish dominance.
Where can someone watch a video of The Offspring performing live?
Someone can watch a video of the Offspring performing live on the video sharing website YouTube. There one can see the music videos for a number of their songs and their live performances.
Do any dinosaurs have live births?
No. Their offspring comes out in eggs.

What is the theme of the song Yellow Submarine?
YELLOW SUBMARINE In the town where I was born, Lived a man who sailed to sea, And he told us of his life, In the land of submarines, So we sailed on to the sun, Till we found the sea of green, And we lived beneath the waves, In our yellow submarine, We all live in a yellow submarine, yellow submarine, yellow submarine, We all live in a yellow submarine, yellow submarine, yellow submarine. And our friends are all aboard, Many more of them live next door, And the band begins to play. (Trumpets play) We all live in a yellow submarine, yellow submarine, yellow submarine, We all live a yellow submarine, yellow submarine, yellow submarine. (Full speed ahead, Mr. Parker, full speed ahead! Full speed over here, sir! Action station! Action station! Aye, aye, sir, fire! Captin! Captin!) As we live a life of ease Every one of us is all we need,(is all we need) Sky of blue, and sea of green,(sky of blue and sea of green) in our yellow(in our yellow) submarine.(submarine) ( Hahaha! ) We all live in a yellow submarine, yellow submarine, yellow submarine, We all live in a yellow submarine, yellow submarine, yellow submarine. (fading) We all live in a yellow submarine, yellow submarine, yellow submarine, We all live in a yellow submarine, yellow submarine, yellow submarine.
