Polygenic?
Natural selection usually acts on the phenotype of polygenic traits as they are suites of genes acting in concert to form a trait. If you had a trait, such as height, in two variant brothers then the aggregate would need to be selected for as the genes working in concert, but not equally well, would render different heights in the brothers which would be then visible to natural selection.

What is another saying of the survival of the fittest?
"Natural selection" is another saying that refers to the survival of the fittest, as individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to future generations.
What is the natural process favoring organisms that are better adapted to their environment?
Natural selection is the process favoring organisms with traits that better suit their environment, leading to the individuals with advantageous traits surviving and reproducing more successfully. Over time, this results in the accumulation of beneficial traits in a population, improving its fitness and adaptation to its environment.
Explain the difference between artificial and natural selection?
Artificial selection is anthropogenic -- humans interfere with nature to determine what traits get passed on, whereas natural selection is when through sexual reproduction the traits passed on are determined by survival of the fittest.
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.
What is the difference between natural and artifical selection?
Natural selection - is allowing the species to breed at their own convenience - with whichever member of the opposite sex they choose. Artificial selection is human intervention in that natural process - allowing breeders to choose the best genes for the species.
Does selection operate on the genotype or the phenotype?
Selection operates on the phenotype, which is the observable characteristics of an organism. Organisms with certain phenotypic traits that increase their fitness are more likely to survive and reproduce, passing on their advantageous traits to the next generation.
Is natural selection responsible for inherited traits?
no, inherited traits are responsible for natural selection
Can natural selection occur in an individual organism?
No, natural selection operates at the population level by favoring certain traits that are passed on through generations. It involves differential reproductive success among individuals with certain traits in response to environmental pressures.
What happens to unnecessary traits during the process of natural selection?
How does natural selection affect undesirable traits?
How are artificial selection and natural selection similar?
Natural selection and artificial selection both involve an organism's traits being determined by how much they're favored. Then, the organisms with favorable traits pass those traits on to future generations.However, natural selection is caused by survival; the organisms with traits that increase their chances for survival and reproduction pass on their traits. As for artificial selection, humans purposefully decide which traits (like the most colorful one) of an organism to pass on.The similarity of artificial selection and natural selection is that they both can cause changes in the frequency of population.
Is a frog an example of natural selection?
No, a frog is not an example of natural selection itself. Natural selection is a mechanism for evolution that acts on populations of organisms over generations, influencing the traits that are passed on to the next generation. Individual organisms like a frog can be impacted by natural selection, depending on their traits and how those traits affect their survival and reproduction.
What is the process where animal select mates with traits best suited for survival?
natural selection. :)
What process in which organisims with traits well suited to an environment are more likely to survive and to produce offspring is?
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
What requires natural selection to occur in a population?
Natural selection requires variation in traits within a population, heritability of those traits, and differential reproductive success based on those traits. Without these components, natural selection cannot act on a population.
Why was natural selection an important contribution to the theory of evolution?
Natural selection was important because it provided a mechanism to explain how evolution occurs. It operates by allowing individuals with advantageous traits to survive and reproduce, leading to the gradual accumulation of those traits in a population over time. This process helps to explain the diversity of life on Earth and how organisms have adapted to their environments.
Does natural selection occur in the world today?
Yes, natural selection is still occurring in the world today. It is an ongoing process where organisms with traits that increase their chances of survival and reproduction are more likely to pass on these traits to future generations. Changes in the environment can also drive natural selection by favoring certain traits over others.
Why did Darwin believe organisims evolved using natural selection instead of required traits?
One of the strongest reasons he had for thinking natural selection was the driving force of evolution in fact he started his book with this concept, was artificial selection. Breeders had long know that traits were heritable and they could select for the traits they wanted by just mating the favored organisms. From this example Darwin knew that acquired traits were neither heritable or selectable.
