Which environmental factor could lead to a decrease in genetic variation in a population of tuna?
Overfishing is an environmental factor that can lead to a decrease in genetic variation in a population of tuna. When specific sizes or species are targeted, it can reduce the effective population size and lead to a loss of alleles. Additionally, habitat destruction and changes in ocean conditions, such as temperature and acidity, can further contribute to the decline in genetic diversity by altering reproductive patterns and survival rates. This reduction in genetic variation can make the population more vulnerable to diseases and environmental changes.

What kind of variation must exist in a population that has a wide range of phenotypes?
Genetic variation must exist within the population, meaning individuals have different alleles. This genetic diversity results in a wide range of phenotypes that can be observed. Environmental factors can also contribute to phenotypic variation within the population.
The traits of organisms in a population naturally change over time what is the source of the variation?
The source of variation in a population comes from genetic mutations and genetic recombination during reproduction. These processes introduce new genetic information, resulting in different traits being passed on to offspring. Environmental factors can also contribute to variation through selective pressures shaping which traits are advantageous.
If a certain species has little genetic variation what could lead to its rapid extinction?
A lack of genetic variation can make a species less able to adapt to changing environmental conditions or new threats like diseases or predators. This reduced ability to adapt increases the species' vulnerability to extinction if they cannot effectively respond to these challenges.
What term describes changes that within species?
The term that describes changes within a species over time is "microevolution." This involves genetic variations that occur within a population, leading to changes in traits or characteristics in response to environmental factors.
How do variation occur in asexually reproducing organisms?
Variation in asexually reproducing organisms can occur through mutations, which are random changes in the genetic material. Additionally, genetic recombination can occur through processes like gene transfer, leading to genetic diversity among the offspring. Environmental factors can also play a role in inducing variations in asexually reproducing organisms.
What would most likely decrease the genetic variations in the human population?
Which would most likely decrease the genetic variation in the human population?
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.
Does natural selection have a tendency to increase or decrease genetic variation within a population?
Natural selection tends to decrease genetic variation within a population by favoring certain traits that are advantageous for survival and reproduction.
When genetic variation increases within a population what will most likely decrease?
When genetic variation increases within a population, the likelihood of inbreeding depression typically decreases. This is because a greater diversity of alleles allows for a more robust gene pool, reducing the chances of harmful recessive traits being expressed. Additionally, increased genetic variation often enhances a population's adaptability and resilience to environmental changes.
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
Which would likely decrease the genetic variation in the human population?
If the human population was reduced to a very small number of interbreeding individual then this small population, denied outbreeding, would have very little genetic variation. Humans, who went through a bottleneck event about 70,000 years ago, are considered a " small " species because they have little genetic variation in comparison to many other species. Google cheetah to see how this concept works.
How can introducing genetic diversity into a population enhance its overall genetic variation?
Introducing genetic diversity into a population can enhance its overall genetic variation by increasing the range of traits and adaptations available within the population. This can help the population better respond to environmental changes and challenges, improving its overall resilience and survival chances.
Which breeding system reduces genetic variation in a population?
Inbreeding is a breeding system that reduces genetic variation in a population. Inbreeding occurs when closely related individuals mate, leading to an increase in homozygosity and a decrease in genetic diversity within the population. This can result in an increased prevalence of genetic disorders and reduced fitness in the population.

Why genetic variation is a benefit to a population?
Genetic variation allows a population to adapt to a changing environment.
What do stabilization selection and disruptive selection have in common?
They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation
Do you no two examples of Inherited variation?
