Devin- Natural selection can lead to individuals with certain combinations of polygenic traits having higher fitness, increasing their likelihood of passing on their genes to the next generation.
- It can drive the frequency of alleles that contribute to favorable trait combinations up or down in a population over time.
- Natural selection can influence the distribution of phenotypic variations for polygenic traits, favoring those that provide a survival or reproductive advantage in a specific environment.

What happens to unnecessary traits during the process of natural selection?
How does natural selection affect undesirable traits?
Traits that are shaped by many genes are called what?
Polygenic traits. These traits are influenced by multiple genes working together to produce a specific phenotype. Examples of polygenic traits include height, skin color, and intelligence.
What is a polygenic selection?
Polygenic selection refers to the process by which multiple genes across the genome contribute to the selection of a particular trait or phenotype. This type of selection can result in a continuous distribution of phenotypic traits within a population. It is common in complex traits like height or intelligence where multiple genetic loci interact to influence the outcome.
How are polygenetic traits inheritated?
Polygenic traits are controlled by multiple genes located on different chromosomes. Each gene contributes a small effect to the trait, resulting in a continuous range of phenotypes. The inheritance of polygenic traits follows the principles of Mendelian genetics, with the combined effect of multiple genes influencing the trait's expression in an individual.
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.
