Which factor does not take a population out of Hardy-Weinberg equilibrium?
Mutation is the factor that does not take a population out of Hardy-Weinberg equilibrium. The other factors that can disrupt equilibrium are natural selection, genetic drift, gene flow, and non-random mating.
Principle states that one factor in a pair may prevent the other factor in the pair from being expressed?
This principle is called the principle of dominance. It explains that in a pair of alleles, the dominant allele will be expressed over the recessive allele. So, the dominant factor will prevent the recessive factor from being expressed in the phenotype.
What is an allele and what is a nasty allele?
Allele is word used by Mendel for counter parts of an elementon later called factor and renamed as gene e.g. T and t are alleles for a gene that controls height in pea plant .Nasty allele is not biological term .Note word elementon is technical term used by Mendel , it is not element used in Chemistry .
What are two processes through which genetic drift can occur?
Random events in small populations and the founder effect. The first can be just about any thing, but the second is about the emigration of a part of a population to another area/population. These emigrants are not fully representative of the parent populations allele frequency; hence drift.Other causes of genetic drift:1- Changes in allele frequency: Sometimes, there can be random fluctuations in the numbers of alleles in a population. These changes in relative allele frequency, called genetic drift, can either increase or decrease by chance over time.Typically, genetic drift occurs in small populations, where infrequently-occurring alleles face a greater chance of being lost.2- population bottleneck : Genetic drift is common after a population experiences a population bottleneck. A population bottleneck arises when a significant number of individuals in a population die or are otherwise prevented from breeding, resulting in a drastic decrease in the size of the population.3-Distribution: How does the physical distribution of individuals affect a population? A species with a broad distribution rarely has the same genetic makeup over its entire range. For example, individuals in a population living at one end of the range may live at a higher altitude and encounter different climatic conditions than others living at the opposite end at a lower altitude.4- Migration: Migration is the movement of organisms from one location to another. Although it can occur in cyclical patterns (as it does in birds), migration when used in a population genetics context often refers to the movement of individuals into or out of a defined population.5-Random chance
If male has type a and female has type ab what are the possible blood types of their offspring?
The blood type will be the same as one of the parents or a combination, so A or AB. If the parents both have the same Rh factor (+ or -) the baby will have that factor, else it could also be either. The risky situation at birth is where the baby's Rh factor is not the same as the mother's.
What factor determines whether the frequency of the new allele will increase?
Which factor might determine whether the frequency of the new allele will increase in a population where a mutation occurs?
Which factor does not take a population out of Hardy-Weinberg equilibrium?
Mutation is the factor that does not take a population out of Hardy-Weinberg equilibrium. The other factors that can disrupt equilibrium are natural selection, genetic drift, gene flow, and non-random mating.
If a mutation introduces a new skin color in a lizard population what factor might determine weather the frequency of the new allele will increase?
Simple put, let us say that color was a better camouflage coloration in any environment the lizard found itself. Then that better camouflage hid the lizard better from its predators. Then those lizards possessing this new mutation would survive longer, have greater reproductive success and drive a larger frequency of these mutant alleles that conferred this advantage into the populations gene pool.
What factor among the following would lead to an increase in the momentum of a photon?
The factor that would lead to an increase in the momentum of a photon is an increase in its frequency.
Which environmental factor can increase the rate of mutation in organism?
Generally i find, factors like being in a museum, with one un-accounted genetically enhanced spider is a likely factor. also barrels of nuclear waste, falling of trucks can also increase mutation rates.
What Wave travels at a constant speed how does the frequency change if the wavelength is reduced by factor of 3?
A wave traveling at a constant speed will have its frequency remain the same regardless of the change in wavelength. The wavelength and frequency of a wave are inversely proportional, meaning if the wavelength is reduced by a factor of 3, the frequency would increase by a factor of 3 to maintain a constant speed.
Is mutagen an environmental factor that causes mutation?
It increases the odds of mutation.
A factor that seems to disappear?
a recessive allele
What is the factor that causes mutation?
radiations
What is a synonym for allele?
allelomorph, gene, cistron, factor
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.
Why high frequency signal is more affected by noise compare to low frquency signal?
AS FREQUENCY INCREASE THE BANDWIDTH INCREASE. AS WE KNOW NOISE HAVE LARGER BANDWIDTH. SO ITS AFFECT HIGH FREQUENCY SIGNAL. BUT LOW FREQUENCY SIGNAL HAVE LOW BANDWIDTH SO IT IS LESS AFFECTED BY NOISE. ALSO WE KNOW QUALITY FACTOR= CUTOFF FREQUENCY / BANDWIDTH. SO AS FREQUENCY INCREASE B.W. INCREASE SO QUALITY DEGRADE. CUTOFF FREQUNCY AND THE TERM FREQUENCY (USED HERE) IS DIFFERENT. CUTTOFF FREQUNCY IS USED IN FILTER. PRABIR KUMAR SETHY prabirsethy.05@gmail.com
