When the mean value of variation is selected, it typically results in stabilizing selection. This type of selection favors individuals with traits that are close to the average, reducing the prevalence of extreme phenotypes. As a result, the population tends to maintain its average traits over time, leading to reduced variation and increased uniformity within the population.
What else can I help you with?
What does a high standard error mean?
It means theres a high amount of variation between the results used to calculate the mean value for a particular sample or experiment
What Conditions necessary for a measure of variation to have a positive value?
It is that the measure is somehow related to the absolute value of the observations compared to some fixed value and also that there IS some variation.
Is it possible for a coefficient of variation of a set of data to be zero Explain.?
Yes it is. If all the observations have the same non-zero value then the coefficient of variation will be zero.
What is the probability that the value of a randomly selected variable from a normal distribution will be more than 3 standard deviation from its mean value?
Approx 0.0027
Describe the conditions necessary for a measure of variation to have the value zero?
The measurements for all members of the sample are the same.
What command retrieves only the records that contain the value in the selected field?
Filter by selection
What is natural selection that acts against one type of extreme form of a polyygenic trait to reduce genetic variation and change the average value of a trait within a population called?
Stabilizing selection is the type of natural selection that acts against extreme forms of a polygenic trait to reduce genetic variation and maintains the average value of the trait within a population. It favors the intermediate phenotype, leading to a narrowing of the range of variation for that trait over time.
What terms describes natural selection that acts against intermediate forms of a polygenic trait to increase genetic variation while not changing the average value of a trait within?
Disruptive selection
What do you call variation that can take any value like height or weight?
Variation that can take any value, such as height or weight, is referred to as continuous variation. This type of variation is characterized by a range of possible values within a given interval, allowing for fractional or decimal measurements. Continuous variation often results from the interplay of multiple genetic and environmental factors.
What is the 3 types of natural selection?
Stabilizing Selection-- The extremes are selected against.Example: height; mostly beings tend to the average height- not too many really short ones or really tall ones.Directional selection-- One extreme value is selected for.Example: speed; faster is always better so a population will tend to get faster over time.Disruptive selection-- The extremes are both selected for.This type of selection is not as common as the first two. Example: Prey-type animal with distinctive markings which the predators know will over time move away from the norm in both directions.
What is Stabilizing Selection and Distruptive selection?
Stabilizing selection is a type of natural selection that favors the intermediate phenotypes in a population, leading to a decrease in genetic diversity. Disruptive selection, on the other hand, favors extreme phenotypes over intermediate ones, resulting in increased genetic variation within a population.
What does a high standard error mean?
It means theres a high amount of variation between the results used to calculate the mean value for a particular sample or experiment
What does the coefficient of the variation tell you?
The coefficient of variation (CV) is a measure of relative variability, indicating the degree of dispersion of a distribution relative to its mean. A high CV value suggests greater variability, while a low CV value suggests more consistency. It is useful for comparing the variability of different datasets with differing units of measurement.
What value you will add to any organisation if selected?
If you are selected, your education and previous experience can add value to an organization.
What place is the selected digit in what is the value of the selected digit 519'534?
3
Can Coefficient of variation of a set of data to be zero?
Yes, if there is no variation: all the data have to have the same value and that value must be non-zero.
What Conditions necessary for a measure of variation to have a positive value?
It is that the measure is somehow related to the absolute value of the observations compared to some fixed value and also that there IS some variation.
