What else can I help you with?
What effect does non-random sample have on what you can say about the results of a study?
It means that the results of the study cannot be claimed to hold for the entire population from which the sample was drawn. The researchers can only claim that their results hold for the individuals selected into their sample.
If a research study is found to not be clinically significant can the research study still be beneficial and if so why would it be beneficial?
It is an indication that there the clinical effect is negligible.
The variation in the population as measured by the standard deviation has little or no effect in determining the size of a sample selected from the population True or False?
The answer is False
Strengths and weaknesses of correlation?
A good starting point to research and very good at showing relationship between variables but doesn't demonstrate cause and effect
What is false consensus effect?
The false consensus effect is a cognitive bias where individuals overestimate the extent to which their beliefs, values, and behaviors are shared by others. This phenomenon leads people to assume that their opinions are more common than they actually are, resulting in a skewed perception of social norms. It can influence decision-making and interpersonal relationships, as individuals may feel validated in their views based on this misperception of consensus.
What is the separation of a small group of individuals from the main population known as?
The separation of a small group of individuals from the main population is known as isolation or founder effect.
Bottleneck effect vs founder effect?
bottleneck effect is an evolutionary event in which population size is radically reduced because of catastrophic events. founder effect occur when few individuals migrate from main population and establishes a separate population in new geographical location. both of these are special cases of genetic drift.
Types of genetic drift?
There are two main types of genetic drift: population bottleneck and founder effect. Population bottleneck occurs when a population's size is drastically reduced, leading to a loss of genetic diversity. Founder effect occurs when a small group of individuals establishes a new population with limited genetic variation.
How does working in antarctica effect the environment?
Research in the Antarctic informs environmental policies for governments representing 80% of the earth's population. The human impact of this research is negligible.
How are the bottleneck effect and founder effect related as examples of genetic drift in population genetics?
The bottleneck effect and founder effect are both examples of genetic drift in population genetics. The bottleneck effect occurs when a large population is drastically reduced in size, leading to a loss of genetic diversity. The founder effect happens when a small group of individuals establishes a new population, leading to a limited gene pool. Both effects can result in changes in allele frequencies and genetic variation within a population.
The type of genetic drift that follows the colonization of a new habitat by a small group of individuals is called?
founder effect. This occurs when a small group of individuals establish a new population, leading to a decrease in genetic variability due to the limited genetic diversity of the founding individuals.
When a small group of individuals leaves the parent establishes a new population is called what?
This is known as founder effect, a phenomenon where a small group of individuals migrates or is isolated from a larger population, establishing a new population with genetic differences from the original population due to the limited genetic diversity of the founding members.
What are two types of genetic drift?
Founder effect- isolation of few individuals from larger population; new population forms with different gene pool. Bottleneck effect- Drastic reduction of population size leading to a restrictive gene pool in wich the population must use to recover. Forms population with different gene pool.
Do grizzly bears effect the lives of polar bears?
Not at the moment, their territories doe not overlap.
What are the differences between the bottleneck effect and the founder effect in terms of their impact on genetic diversity within a population?
The bottleneck effect occurs when a large population is drastically reduced in size, leading to a loss of genetic diversity. The founder effect happens when a small group of individuals establishes a new population, resulting in a limited gene pool. Both effects can reduce genetic diversity, but the bottleneck effect is caused by a sudden event, while the founder effect is due to the small initial population size.
How do the founder effect and the bottleneck effect differ, particularly in the context of genetic diversity and population size?
The founder effect occurs when a small group of individuals establishes a new population, leading to reduced genetic diversity. The bottleneck effect happens when a population undergoes a drastic reduction in size, also resulting in decreased genetic diversity. The main difference is that the founder effect involves the initial establishment of a population, while the bottleneck effect involves a sudden decrease in population size. Both effects can lead to genetic drift and increased risk of genetic disorders.
What characteristic do a bottleneck and a founder effect have in common?
The founder effect a genetic bottleneck are similar in their effect on the genetic diversity of a local population in both situations. They result in the development of a population from a small number individuals and is likely to have reduced genetic diversity.
