10. In the Hardy-Weinberg equation, what does q stand for? 1. How do we measure and define evolution?2. Evolution occurs:1. at the level of the individual.2. in traits.3. in a single generation.4. only at the phenotypic level.3. The only source of entirely new genetic material is:1. natural selection.2. mutation.3. recombination.4. genetic drift.4. Which of the following is not a key component of natural selection?1. Traits for strength and vitality are favored over other traits.2. Random variation exists for every trait in a population.3. There will always be competition for resources.4. Those with advantageous traits will outreproduce others.5. The founder effect is a specific type of:1. gene flow.2. meiosis.3. genetic drift.4. mutation.6. When a substantial amount of genetic variation is lost, we call it a:1. genetic die-off.2. gene flow.3. genetic bottleneck.4. gene dam.7. When two previously isolated populations begin interbreeding andexchanging genes, we call it:1. genetic drift.2. founder effect.3. incest.4. gene flow.8. List two of the seven key conditions necessary for a trait to be inequilibrium.9. In the Hardy-Weinberg equation, what does p stand for?

Natural selection can cause evolution, but evolution is not always caused by natural selection. 1)True 2)False
1) What does the term Natural Selection mean? Select one: a.The number and relative frequency of alleles present in a particular population. b.The process through which individuals with certain traits tend to produce more surviving offspring that individuals without those traits. c. Any change in the hereditary material of an organism.
explain the following mechanism of evolution: 1. mutations 2. gene flow 3. genetic drift 4. sexual selection 5. natural selection
1. Why do you think it is necessary for there to be variation in a population in order for evolution by natural selection to occur? 2. Why is it necessary for traits to be inherited for evolution to take place? 3. If a population is already well adapted to its environment, will most mutations be helpful or harmful? Explain.
In the time of Darwin the results of Mendel’s research on biological inheritance had not been published, Genetics was not yet developed, neither DNA nor the concept of genetic mutation were known. What is the modern darwinist theory that incorporates these bodies of knowledge?

What are the missing words about evolution? 1. Simple life forms first appeared on Earth over 3 A years ago. 2. Individuals in a population of a species show differences in the characteristics. This is called B 3. Natural selection enables individuals with characteristics most suited to their environment to survive and reproduce. 4. C for useful characteristics are more likely
Natural Selection Fill in the blanks to explain Darwin's theory of Natural Selection using these words: DNA, survive, variation, DNA, reproduce 1. Individuals in a species show 2. This is because of differences in their 3. Individuals with characteristics which suit the environment are more likely to and 4. So the from these individuals is passed onto the next generation.
Darwin proposed natural selection as a mechanism for evolution. How is it similar to artificial selection? How is it different?For natural selection to work, there must be genetic variation within a population as well as mutations? Why must there be both?
