Evolutionary Analysis Exam 2 fully solved 2023 passedgenetic variation - correct answer differences in alleles or genotype as shown by various phenotypes How was genetic variation studied early on? - correct answer they studied proteins, because different proteins are produced by genetic variations. (doesn't show variation in substitutions though) allele example - correct answer B, b genotype example - correct answer BB, Bb, bb environmental variation - correct answer if a phenotype changes because of the environment it is in, there is environmental variation -for example, someone who is blonder in sunny places than in less sunny places. genotype by environmental variation - correct answer when different genotypes respond differently to the environment. For example, maybe BB shows differences in different environments, but bb remains constant. plasticity - correct answer the degree a trait can evolve. So when a specific organism changes under different environments, it is NOT evolution. It is an evolved genotype to help organisms survive in environments that change a lot. canalization - correct answer a trait is selected against if it isn't beneficial to the environment, so if plasticity isn't beneficial, then traits would remain constant in different environments. think about a way you could create a study to test genetic, environmental, and genotype by environmental variation - correct answer If we have a series of plants with different genes: 1. Keep the environment constant, and see if variation occurs due to differences in genes
