Answer:
The closer together different genetic sequences are in the same chromosome the smaller is the chance of crossing-over/recombination among them
Explanation:
Genetic linkage refers to genetic sequences which are located on the same chromosome, and thereby they are usually inherited together during meiosis. On the other hand, crossing over (also known as recombination) refers to the exchange of chromosome fragments between non-sister chromatids during meiosis. In consequence, the closer together two genetic sequences are on the same chromosome, the lesser will be the chance they will be separated by crossing-over.
Answer:
A. Independent variable 2. dominant tree species
B. Dependent variable 3. tree survival rate after the fire
C. Controlled variable 1. thinning or no thinning before the fire elevation of the site
Explanation:
A. An independent variable doesn't undergo changes during the experiment because it is not conditioned by other variables in the experiment. In this example, dominant tree species represent a variable that is independent of the experiment itself.
B. A dependent variable is those that you need to measure and depends on the other factors in the experiment. In this example, tree survival is dependent on the factors that affect the results (i.e. humidity in the trees, presence of resinous material in the trees that are non-combustible, etc.)
C. A controlled variable is those that we use to observe an expected outcome in the experiment and therefore it is used to compare with the test group. In this case, thinning or no thinning are used as positive and negative controls, respectively, because they enable their comparison with the test group in the experiment.
