What must be true for hardy equilibrium to occur?
mating must happen randomly
What must occur for a population to grow?
For a population to grow, the birth rate must exceed the death rate, there must be enough resources available to support the increase in population, and factors that limit growth such as disease or predation must be controlled.
What are the four things that must happen for natural selection to occur?
For natural selection to occur, there must be genetic variation present in a population, some of which is heritable. This variation must lead to differences in survival and reproduction (differential fitness). Individuals with advantageous traits must pass those traits on to their offspring. Over time, these advantageous traits become more common in the population.
In order for evolution to occur in a population individuals with a trait that is naturally selected for must?
Individuals with the beneficial trait must survive and reproduce at a higher rate than those without the trait. This differential reproductive success leads to an increase in the frequency of the advantageous trait in the population over time, allowing for evolution to occur.
What condition is necessary for genetic drift to have a significant effect on a population A natural disaster must occur. The population needs to be small. Gene flow must occur. A portion of the p?
The condition necessary for genetic drift to have a significant effect on a population is when the population size is small. In smaller populations, genetic drift can lead to random changes in allele frequencies, impacting the overall genetic diversity of the population.
What conditions must be met for a spontaneous process to occur?
For a spontaneous process to occur, the conditions must involve an increase in entropy and a decrease in free energy.
What must happen for specification to occur?
A population must be isolated in some way
What must be true for hardy equilibrium to occur?
mating must happen randomly
What is the word for decrease in population?
The term for a decrease in population is "population decline." This phenomenon can occur due to various factors such as high mortality rates, low birth rates, emigration, or a combination of these. Population decline can have significant social, economic, and environmental impacts on a region or country.
What must occur for a gene pool within a population to change?
A genetic mutation within the population.
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
What does natural decrease mean?
Natural decrease refers to a situation where the number of deaths in a population exceeds the number of births over a specific period. This results in a decline in the population size, which can occur due to factors such as low fertility rates, an aging population, or increased mortality rates. Natural decrease is often used to describe demographic trends in certain countries or regions experiencing population decline.
What must occur for a population to grow?
For a population to grow, the birth rate must exceed the death rate, there must be enough resources available to support the increase in population, and factors that limit growth such as disease or predation must be controlled.
What will happen if the plankton population decrease?
The population of zoo plankton would decrease.
How would a decrease in natality change the population?
A decrease in the birth rate will cause a decrease in population over time.
What must occur for the gene pool within population to change?
natural selection or genetic drift
Possible reasons why a rabbit population may decrease?
Death and migration are factors that can decrease hare population.
