One of the conditions of natural selection is that variant organisms are selected on their superior adaption to the environment, reproductive success and their passing on of these traits to progeny, as populations evolve. A genetic component is the physical molecule that is inherited by progeny which reflects their parents successful trait. This is the '' hard '' inheritable component of behavior.
What else can I help you with?
What are the 4 types of natural selection?
The four types of natural selection are stabilizing selection (where the average phenotype is favored), directional selection (where one extreme phenotype is favored), disruptive selection (where both extreme phenotypes are favored), and sexual selection (where traits that increase mating success are favored).
What is the result of artificial selection?
Artificial selection results in the intentional breeding of plants or animals for specific desired traits. Over time, this can lead to changes in the genetic makeup of a population, resulting in organisms with traits that are favored by humans.
What do stabilization selection and disruptive selection have in common?
They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
What are defactors that affect the process of natural selection?
Some factors that can affect the process of natural selection include mutation rate, genetic diversity within a population, environmental changes, competition for resources, and presence of predators. These factors can influence which traits are favored or selected for in a population over time.
What is a component of innate behavior?
genetic
What resulted from a genetic variation that was favored by natural selection?
The genetic variation that was favored by natural selection led to the increased frequency of the advantageous trait in a population over time, resulting in adaptation to the environment. This can lead to improved survival and reproductive success for individuals carrying the advantageous variation.
Stabilizing selection results in more or less genetic diversity?
Stabilizing selection typically results in less genetic diversity because it selects against extreme phenotypes, narrowing the range of traits present in a population. This leads to the preservation of intermediate phenotypes that are favored by the selective pressures, reducing overall genetic variation.
What are the 4 types of natural selection?
The four types of natural selection are stabilizing selection (where the average phenotype is favored), directional selection (where one extreme phenotype is favored), disruptive selection (where both extreme phenotypes are favored), and sexual selection (where traits that increase mating success are favored).
Which of the following resulted from a genetic variation that was favored by natural selection?
The development of antibiotic resistance in bacteria is a result of genetic variation that was favored by natural selection. Bacteria that had a mutation making them resistant to antibiotics were able to survive and reproduce, passing on this trait to future generations. Over time, this led to the prevalence of antibiotic-resistant strains in bacterial populations.
The mode of natural selection in which both extremes in the range of a phenotype are favored is termed?
That would be disruptive selection.
What is the result of artificial selection?
Artificial selection results in the intentional breeding of plants or animals for specific desired traits. Over time, this can lead to changes in the genetic makeup of a population, resulting in organisms with traits that are favored by humans.
Is behavior inherited?
Behavior can be influenced by both genetic and environmental factors. While some behaviors can have a genetic component and be inherited, environmental influences also play a significant role in shaping behavior. The interaction between genes and the environment ultimately determines an individual's behavior.
What do stabilization selection and disruptive selection have in common?
They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
What is the difference between purifying selection and positive selection in the process of natural selection?
Purifying selection removes harmful genetic variations, while positive selection promotes beneficial genetic variations in natural selection.
