If the mutation causes a characteristic that is carried as a dominate trait, then it can spread through a population. Also, if the characteristic that is brought about by the mutation is beneficial, the organism will be better suited to its environment than others. If the organism passes this trait to its offspring, then it is understood that they should survive in a greater ratio than those without the trait and the trait becomes common.

How does natural selection favor an organism's heritable trait?
Natural selection favors a trait by increasing its frequency in a population. Natural selection is differential reproductive success. If one variant of a trait enables an organism to have and raise more offspring successfully than other variants in a particualr environment, then it will become more common in the population.
How does positive vs negative frequency-dependent selection impact the evolution of a population?
Positive frequency-dependent selection occurs when the fitness of a trait increases as it becomes more common in a population, leading to the trait becoming more prevalent over time. This can promote the evolution of cooperation and mutualism. In contrast, negative frequency-dependent selection occurs when the fitness of a trait decreases as it becomes more common, leading to the maintenance of genetic diversity in a population. This can prevent the fixation of a single trait and promote the coexistence of multiple traits within a population.
Differences in heritable trait arise trough?
Differences in heritable traits can arise through genetic mutations, recombination of genetic material during sexual reproduction, and environmental influences that interact with genetic factors. These variations can lead to differences in physical characteristics, behaviors, and other traits within a population.
Which trait, if either, is likely to respond to selection?
Traits that are heritable are more likely to respond to selection, as they can be passed down from one generation to the next. Non-heritable traits are less likely to respond to selection, as they are not influenced by genetic factors.
What four conditions must be present for natural selection to result in a difference in reproductive success?
Variation: There must be genetic variation for a particular trait within a population. Inheritance: The trait must be heritable and passed down from one generation to the next. Differential reproductive success: Individuals with a certain trait must have higher reproductive success than those without it. Selection pressure: Environmental factors must exert pressure favoring individuals with the advantageous trait, leading to its increased frequency in the population over time.
What I a heritable trait that increases individual fitness called?
A heritable trait that increases individual fitness is called an "adaptive trait" or "adaptation." These traits enhance an organism's ability to survive and reproduce in its environment, thereby increasing its fitness. Over generations, adaptive traits can become more common within a population through the process of natural selection.
Natural selection can only act upon a certain trait if the trait is?
Heritable, meaning that it can be passed down from one generation to the next through genetic inheritance. Without a genetic basis, natural selection would not be able to change the frequency of that trait in a population over time.
How does natural selection favor an organism's heritable trait?
Natural selection favors a trait by increasing its frequency in a population. Natural selection is differential reproductive success. If one variant of a trait enables an organism to have and raise more offspring successfully than other variants in a particualr environment, then it will become more common in the population.
What Is a heritable trait that confers on an individual a survival and reproduction advantage in its current environment?
A heritable trait that confers a survival and reproduction advantage is camouflage in animals. For example, a moth that matches the color of its environment can avoid predators more effectively, increasing its chances of survival and reproduction. This trait can be passed on to offspring, leading to a population that is better adapted to its surroundings. Over time, such traits can become prevalent in the population through natural selection.
What three factors must a trait have to evolve?
For a trait to evolve, it must exhibit variation within a population, be heritable so that it can be passed on to the next generation, and confer a fitness advantage that increases the likelihood of survival and reproduction. These factors ensure that the trait can be selected for over time, leading to evolutionary changes in the population.
What is a permanent heritable change in an allele that produces a different variant of the same trait?
A permanent heritable change in an allele that produces a different variant of the same trait is called a mutation. Mutations can lead to genetic diversity within a population and are the raw material for evolution.
How does positive vs negative frequency-dependent selection impact the evolution of a population?
Positive frequency-dependent selection occurs when the fitness of a trait increases as it becomes more common in a population, leading to the trait becoming more prevalent over time. This can promote the evolution of cooperation and mutualism. In contrast, negative frequency-dependent selection occurs when the fitness of a trait decreases as it becomes more common, leading to the maintenance of genetic diversity in a population. This can prevent the fixation of a single trait and promote the coexistence of multiple traits within a population.
What can cause particular trait to become more common in a population?
When it comes that a particular trait being spread though a population, it is called reproduction.
A is an inherited trait that helps an organism survive and reproduce in its particular environment?
This trait likely confers a survival advantage on individuals possessing it, increasing their chances of surviving and reproducing in their specific environment and passing on the trait to offspring. Over generations, this can lead to the trait becoming more common in the population as those with it are more successful in passing it on.
Which trait most common in humans?
The most common trait in humans is having five fingers on each hand. This trait is found in the vast majority of the human population worldwide.
What term is used to describe an organism that pass the same trait over many generations?
An organism that passes the same trait over many generations is said to exhibit genetic heritability or have a heritable trait.
Differences in heritable trait arise trough?
Differences in heritable traits can arise through genetic mutations, recombination of genetic material during sexual reproduction, and environmental influences that interact with genetic factors. These variations can lead to differences in physical characteristics, behaviors, and other traits within a population.
