What else can I help you with?
True or False When a population is in genetic equilibrium there is no genetic variation among individuals in that population?
True
Which of these is not a source of genetic variation in a population?
The answer is sexual reproduction
What increases genetic variations?
A large population increases genetics variation. Mutation will also increase genetics variation.
Which procedure can not be used to increase genetic variation?
If a population dwindles, there is low genetic variation and a species may risk extinction.
What tends to increase genetic variation in a population?
Genetic variation is the total amount of genetic diversity present within a species or population. The amount of genetic variation in a population will depend on a variety of factors, including the size of the population, the type of reproduction, and environmental influences. The primary way to increase genetic variation in a population is through mutation. Mutations are random changes in the genetic code that can lead to new traits or characteristics. Mutations can be caused by environmental factors, such as exposure to radiation or chemicals, or they can occur spontaneously. Mutations can be beneficial, neutral, or detrimental to the organism, but they do lead to increased genetic variation. Another way to increase genetic variation in a population is through migration. When individuals from different populations mate, they bring with them different alleles from their home population, increasing the genetic diversity of the new population. This is especially important for populations that are geographically isolated, such as island populations. Another factor that can increase genetic variation is sexual selection. This is the process by which individuals select mates based on certain desired traits. This can lead to an increase in the number of different alleles in the population, as individuals with certain traits will be more likely to reproduce. Finally, gene flow is a process that can increase genetic variation in a population. Gene flow is when individuals from one population move to another population and mate with individuals in the new population. This can bring in alleles from the original population, increasing the genetic diversity of the new population. Overall, while mutation, migration, sexual selection, and gene flow are all important factors in increasing genetic variation in a population, it is important to note that genetic variation can also be decreased by inbreeding and genetic drift. Inbreeding is when individuals mate with close relatives, reducing the number of alleles in the population and leading to decreased genetic variation. Genetic drift is when random fluctuations in allele frequencies occur due to a small population size, leading to decreased genetic variation. Therefore, it is important to consider all of these factors when trying to increase genetic variation in a population.
Where is genetic variation stored in population?
In the gene pool
How large should the sample be to be large enough?
Span the full spectrum of a population's genetic variation. <apex> Reflects the genetic variation of a population...
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
What would decrease genetic variation in a population?
Inbreeding, genetic drift, and natural selection can decrease genetic variation in a population by reducing the number of different alleles present. These processes can lead to a loss of genetic diversity and increase the prevalence of certain genetic traits within the population.
True or False When a population is in genetic equilibrium there is no genetic variation among individuals in that population?
True
Which of these is not a source of genetic variation in a population?
The answer is sexual reproduction

What id genetic variation?
Genetic Variation is a measure of the genetic differences there are within populations or species. For example, a population with many different alleles at a locus may be said to have a lot of genetic variation at that locus. Genetic variation is essential for natural selection to operate since natural selection can only increase or decrease frequency of alleles already in the population
What two different sources of genetic variation in a plant or animal population?
The main source of genetic variation is a large population with a large gene pool.
What increases genetic variations?
A large population increases genetics variation. Mutation will also increase genetics variation.
Which procedure can not be used to increase genetic variation?
If a population dwindles, there is low genetic variation and a species may risk extinction.
What type of population is most susceptible to loss of genetic variation?
Small Population
