Remember that understanding is explanations more than facts. Definitions of phenotype, genotype, allele, gene, microevolution, macroevolution Know that in humans, most of the genetic variation is observed within populations, and know why that is. Know the 4 processes of evolution (3 neutral + natural selection) Know that evolution isn't progressive and doesn't necessarily lead to more complexity Know that evolution can lead to traits that decrease survival (ex: sexual selection) Know that quantitative traits are generally influenced by (i) many genes, each having a small effect on the trait value; and (ii) the environment What is F1 like when you cross 2 homozygotic lines of peas of different colors? What is F2 like when you cross F1 individuals (remember what 9:3:3:1 is about) Know what genetic dominance is about Definitions of chromosome, nucleus, mitosis, meiosis, crossing over How many chromosomes in humans?

Background: In class we did a project about m and m’s and there ability to evolve and natural selection. (Yes I know they can’t actually evolve it was just used as a example in class) however I can’t figure out this question. Occasionally a mutant may occur and produce a candy that is misshapen or Pointier or flatter than the rest. Often this proves to be a weakness, but a rare mutation may confer extra M&M durability. Other mutations in M&Ms could occur ( like ones that result in a new color). A mutant un you population represents a new _________. What goes in the blank
. The Process of Evolution by Natural Selection – Be able to explain the process of evolution by natural selection as it applies to a specific living thing using the outline below: Natural variations caused by random mutations (adaptations) in DNA exist within populations. Those with helpful adaptations survive an environmental change (maybe a predator.) The survivors breed, passing on the inherited mutation (adaptation) to offspring. The resulting population has more of the successful inherited mutation (adaptation) than the original population. Phylogenetic Trees Infer evolutionary relationships of living things by interpreting phylogenetic trees. Know the divisions of hierarchical classification. (DKPCOFGS) c. Differentiate between homologous and analogous (caused by convergent evolution) structures

What is variation? Give its importance. What are the possible causes of variations? Give specific examples. How would you know or identify if the cause of variation is genetic, environmental, or both? Classify these variations as to "species characteristics" or "individual characteristics".

rn.genetics.utah.edu/content/evolution/barriers/ 3. Reproductive isolation reduces GENE FLOW between populations This means that each subpopulation evolves separately and can result in a new species. Isolating mechanisms fall into the following categories. For each category, identify which example(s) from the chart above matches it. Reproductive isolation: physiology prevents mating or producing fertile offspring. Ex. shape or reproductive organs not compatible Temporal isolation - timing isolation, individuals mate at different times of year. Example. frogs that mate in may versus those that mate in July. Behavioral isol -behaviors prevent mating. Ex. birds recognize mates by songs or dance Still confused?

How is variation different from adaptation? * No answer Variation is always caused by mutation while adaptation is a heritable trait. Variation is a difference within an individual organism from the rest of the population. An adaptation is a feature that helps an organism survive in its environment. Adaptation is a difference within an individual organism from the rest of the population. A variation is a feature that helps an organism survive in its environment. Variations are physical or behavioral traits that make an organism better suited to its environment while adaptation comes from random mutations.

Lithobates clamitus. also know as the green frog and bronze frog can range in in skin color from pure to brown to pure green and a mixture of both. As their habitats change frogs with a mixture of both colors have a higher fitness as they are better able to hide from predators. 1. If the change in the distribution of this trait is the result of natural selection, name the mode of selection (ie: Balancing, Disruptive, etc...) 2. If a small group of male frogs end up joining this population from a different population of frogs, which process of selection describes the movement of alleles present in the male frog? 3. The process you named in “c” ________ the genetic variation in the population that the male frog joined? (increase, decrease, or stay the same?)
