The immigrating individuals do not at all interact with the pre-existing population in any way.

The movement of organism into a given area from another area is called?
Population Shift
What are the conditions that must be met for a population to stay in genetic equilibrium?
Hardy-Weinberg equlibrium is reached and maintained under the following conditions:Large populationRandom matingNo mutationNo natural selectionNo emigration/immigration
Which is one of the conditions for Hardy-Weinberg equilibrium?
1.The population must be infinitely large 2. There must be no mutations 3. Breeding amongst the population must be random 4. There must be no Immigration or Immigration There are more conditions so let me know if you need the rest Mutation cannot occur
What is phenotype frequency?
A ratio of individuals with a particular phenotype to the total number of individuals in the population. Individuals with certain phenotype --------------------------------------------------- (Over) Total # of individuals within the population The distribution of traits in a population
When a population is not evolving what is it called?
Hardy-Weinberg equilibrium
The movement of individuals from a population is?
Immigration
When individuals join a population is called?
immigration
True or False When a population is in genetic equilibrium there is no genetic variation among individuals in that population?
True
The movement of individuals from one population to another is called?
Moving out of a population is called emigration. (Moving into a population is called immigration.)
How is population size in an ecosystem determined by the relative rates of birth immigration emigration and death?
Birth and immigration both add individuals to a population, increasing the population size. Similarly, deaths and emigration remove individuals, reducing the population. So growth would be equal to the sum of immigration and births, minus the sum of emigration and deaths.
The movement of organism into a given area from another area is called?
Population Shift
Identify the four processes that determine population growth: immigration, birth, emigration, and death, and explain the impact of each on population size. (14.3)?
Immigration and birth increase the population size as they are bringing more individuals into the population. While death and emigration decrease the population because death kills off individuals while emigration is a process in which individuals leave/exit the population.
How does Immigration and emigration and natality rate and mortality rate affect population?
Immigration and higher natality rates increase population, while emigration and higher mortality rates decrease it. Immigration brings in new individuals, boosting population, while emigration removes individuals, decreasing population. Higher natality rates lead to more births, contributing to population growth, whereas higher mortality rates result in more deaths, reducing the population size over time.
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.
Would a dominant allele ever return to a population?
If a population does not have a particular dominant allele, it could return to the population through the immigration of new individuals carrying the dominant allele.
What are the conditions that must be met for a population to stay in genetic equilibrium?
Hardy-Weinberg equlibrium is reached and maintained under the following conditions:Large populationRandom matingNo mutationNo natural selectionNo emigration/immigration
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.
