What are ways in which natural selection operates on ploygenic traits?

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.

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 evidence of natural selection is available today that was not available to Darwin?
organisms inherit traits
How do a group of organisms that are separated from the rest of its species evolve different traits?
They evolve and adapt so they have traits hat are useful to them, by Natural selection. This means that members of a species that are isolated, well, natural selection makes those with the best chances for survival mate with each other and produce offspring with that trait.
List the three conditions that are necessary and sufficient for natural selection to act on a?
A beneficial mutation leading to variability in a population and the heritability of those beneficial traits.
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.
Is natural selection responsible for inherited traits?
no, inherited traits are responsible for natural selection
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.
What process in which organisims with traits well suited to an environment are more likely to survive and to produce offspring is?
natural selection
What is the process where animal select mates with traits best suited for survival?
natural selection. :)
Does inheritance of acquired characteristics express the concept of natural selection?
No. Natural selection is the differential reproductive success of varying inherited traits. Acquired traits do little to affect the inheritance of traits, except through epigenetics.
What is the process in which traits are chosen to be inherited in evolution?
Natural Selection
The only traits that can lead to natural selection and evolution are traits that?
influence either survival or reproduction.
What variations do natural selection depend on?
They depend on natural variation in traits due to mutation.
How evolution occurs via natural selection?
Evolution occurs via natural selection when certain traits become more favorable in a population over time. This is typically due to the environment or natural selection pressures in the population. Natural selection works by favoring individuals with traits that are better suited to the environment while those with less favorable traits may die off or be less likely to reproduce. Over time these favored traits become more common while unfavorable traits become less common. This process eventually leads to evolution as the population changes to adapt to its environment. The three main components of natural selection are: Variation: Individuals within a population have different traits Inheritance: Traits are passed from generation to generation Differential Reproduction: Traits that are more favorable are more likely to be passed onNatural selection is an ongoing process as the environment is constantly changing and influencing the traits of the population. It is important to note that natural selection is not a directed process and does not necessarily lead to a specific outcome. The result of natural selection is determined by the environment and the traits that are favored in the population.
What is the process in which human breed organisms for certain traits?
The process by which humans breed organisms to obtain certain traits is known as artificial selection.
How gentic traits inheritance differ in natural selection vs selective breeding?
Natural Selection is different from Selective Breeding beacuse the environment controls the traits the animal or plant gets. Selective Breeding is the traits desired are the ones bred
