In nature, selective pressure for or against a single-gene trait that is dominant, or partially expressed in the phenotype will drive the success or failure of that gene to be replicated through reproduction. Over generations, this gene will increase or decrease in relative frequency which may contribute to evolutionary changes within a species.

What is the name for the process where the organism best adapted to their environment to survive?
The process is called natural selection, where organisms that are best adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation.
How does sexual selection differ from natural selection in shaping the evolution of species?
Sexual selection and natural selection are both mechanisms that drive evolution, but they differ in their focus. Natural selection acts on traits that increase an organism's chances of survival and reproduction in its environment, while sexual selection specifically targets traits that enhance an individual's ability to attract mates and reproduce. This can lead to the evolution of characteristics that may not necessarily improve survival, but increase reproductive success.
What is another word for Darwin's theory of natural selection?
Evolution by natural selection.
How is directional selection related to the process of evolution?
Directional selection is a type of natural selection where individuals with traits that are better suited to their environment have a higher chance of survival and reproduction. This process can lead to the evolution of a population over time as certain traits become more common in the gene pool.
How does indirect selection play a role in the evolution of species?
Indirect selection in evolution occurs when a trait that is not directly related to survival or reproduction becomes advantageous due to its association with other beneficial traits. This can lead to the spread of the trait through a population over time, ultimately contributing to the evolution of a species.
What was Charles Darwin's investigation?
Evolution and the theory of natrual selection
Which is NOT a process that is part of modern laboratory genetics?
natrual selection
What are the four processes that lead to evolution?
Mutation, Natural Selection, Migration, and Genetic Drift.
What is the name for the process where the organism best adapted to their environment to survive?
The process is called natural selection, where organisms that are best adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation.
What does natural selection lead to?
Natural selection leads to evolution by giving the organism that is best suited for the area to thrive. Thus those who not suited for the area die off and evolution moves forward.
Is natural selection a cause of evolution?
No, natural selection is believed to result in evolution.
What is a natural selection results?
Adaptions that lead to greater survivability and reproductive success in the immediate environment of the individual organisms under selection pressure.
How does sexual selection differ from natural selection in shaping the evolution of species?
Sexual selection and natural selection are both mechanisms that drive evolution, but they differ in their focus. Natural selection acts on traits that increase an organism's chances of survival and reproduction in its environment, while sexual selection specifically targets traits that enhance an individual's ability to attract mates and reproduce. This can lead to the evolution of characteristics that may not necessarily improve survival, but increase reproductive success.
Can natural selection exist with out evolution?
Perhaps not, but evolution can exist without natural selection.
What is another word for Darwin's theory of natural selection?
Evolution by natural selection.
What is the relationship between evolution and natural selection?
Evolution is the process of change in species over time, while natural selection is a mechanism by which evolution occurs. Natural selection acts on genetic variation within a population, favoring traits that increase an individual's chances of survival and reproduction in a given environment. Over time, these advantageous traits become more common in the population, leading to evolutionary change.
How is directional selection related to the process of evolution?
Directional selection is a type of natural selection where individuals with traits that are better suited to their environment have a higher chance of survival and reproduction. This process can lead to the evolution of a population over time as certain traits become more common in the gene pool.
