  1. why more fit individuals are more likely to have more offspring
  2. why alleles that confer beneficial traits or behaviors are selected for by natural selection
  3. why some deleterious mutations are maintained in the population
  4. why individuals of one sex develop impressive ornamental traits

What are the similarities and differences between natural selection and selective breeding?
Identifying genes like HMGA2 is important, because it is evidence of natural selection. How does it demonstrate that natural selection occurred in Darwin’s finches?   Scientists mutate and modify the gene in the lab to see how changes might occur to the organism. Scientists identify different forms of the gene in individuals from the same species and observe how it shows up as a trait. Scientists study similar genes that also impact the same traits to see how they work together and influence one another. Scientists observe the frequency of the different forms of the gene and how it changes in response to the environment.   Need some help on this one.
In order for a trait to evolve via natural selection, which of the following must be true regarding the trait? (this is a multiple answer question - so select all correct) Group of answer choices There must be variation in the trait. The trait must make the organism survive longer than organisms with different traits. The trait must confer a reproductive advantage on the bearer of the trait. The trait must be heritable. The trait does not necessarily need to be passed down to offspring.
