What else can I help you with?
True or false that random mating leads to microevolution?
False. Random mating itself does not lead to microevolution; it typically maintains genetic variation within a population. Microevolution occurs due to factors such as natural selection, genetic drift, mutation, and gene flow, which can change allele frequencies over time. Random mating helps ensure that these processes can occur without the influence of selective mating patterns.
Is a stratified random sample preferable to a simple random sample when there are known subgroups within the population that the researcher thinks may inpact the results?
Yes, a stratified random sample is preferable when there are known subgroups within the population that may impact the results. This method ensures that each subgroup is adequately represented in the sample, allowing for more precise estimates and insights. By controlling for these subgroups, researchers can minimize potential biases and improve the validity of their findings.
What are advantages and disadvantages of systematic sampling?
It can interact with a hidden periodic trait within a population hence the technique will be compromised since there will not be random and representativeness of the saple
What is the probability that a random chosen family has income less than 72000?
The answer depends on the currency unit involved and the population from which the random family is selected. Within most countries, there is considerable variation in incomes between different regions.
What is the probability that a random chosen family has income between 60000 and 72000?
The answer depends on the currency unit involved and the population from which the random family is selected. Within most countries, there is considerable variation in incomes between different regions.
What does a random distribution of individuals in a population most likely result from?
A random distribution of individuals in a population typically results from factors such as random mating, random dispersal, and random environmental conditions. This can lead to a lack of distinct patterns or clustering in the distribution of individuals within a given area.
True or false that random mating leads to microevolution?
False. Random mating itself does not lead to microevolution; it typically maintains genetic variation within a population. Microevolution occurs due to factors such as natural selection, genetic drift, mutation, and gene flow, which can change allele frequencies over time. Random mating helps ensure that these processes can occur without the influence of selective mating patterns.
Is it true that random mating leads to micro-evolution?
Yes, random mating can contribute to micro-evolution by altering allele frequencies within a population over time. It introduces genetic variation, which can drive evolution through mechanisms like genetic drift and gene flow.
The allele frequencies of a population are more likely to remain unchange if?
There is no evolution. Random mating, no immigration/emigration, or, in short, Hardy-Weinberg equilibrium holds.
What conditions are necessary for populations to remain in hardy Weinberg equilibrium?
Mutation cannot occur
Breeding within only a narrow band of the population demonstrates what?
nonrandom mating
Breeding within only a narrow band of population demonstrayts?
Nonrandom mating
What Breeding within only a narrow band pf the population demonstrates what?
A) Nonrandom mating
How many generation is required of a random mating to reach equilibrium if the population if the population is not in equilibrium?
In a non-equilibrium population, the number of generations needed for random mating to reach equilibrium depends on various factors such as population size, selection pressure, genetic diversity, and mutation rate. It can range from a few generations to many generations, and sometimes equilibrium may not be reached due to ongoing evolutionary forces.
What species have no mutations large population natural selection random mating no movement?
Sounds like a species in Hardy-Weinberg equilibrium.
What must be true for equilibrium to occur?
No disruptive circumstances must be present in random mating in a population for Hardy-Weinberg equilibrium to occur. Mating must happen randomly. No allele can give an advantage
Which does breeding within only a narrow band of the population demonstrates?
Nonrandom mating:) THC<3
