A) What is microevolution and how would you contrast microevolution with macroevolution?

B) •What does it mean to say, “individuals are selected, but populations evolve”?

C) •What is the smallest unit of evolution? What is a population? What is the modern synthesis? How has it contributed to our understanding of evolution?

d): Genetic variation makes evolution possible. •Why is genetic variation so important to evolution?

E) Explain how mutations are the ultimate source of new alleles. •How does sexual recombination produce variation?

a.) Explain the role of positively charge ions (e.g. Ca2+, Li+) used during chemical transformation of E. coli and yeast.

b.) What is the role of i) PEG (Polyethylene glycol) and ii) carrier DNA in yeast transformation?

c.) What is phenotypic expression time in transformation procedure? Explain biological background of it.

d.) Briefly describe two groups of selection markers used for microbial transformation: chemical (antibiotic) resistance and auxotrophic. Explain main principles and selection requirements for each group.

e.) Is phenotypic expression time essential in all transformations? Explain using examples for E. coli ampicillin vs kanamycin, for yeast auxotrophic vs antibiotic resistance markers.

f.) While selecting transgenic plants (Arabidopsis) from transformed seeds, we plated/seeded them directly on selective media plates without phenotypic expression time. However we are looking for antibiotic (hygromycin) resistance. Explain why selection from plant seeds does not require phenotypic expression time.

(SLO 2) In a single population of locusts, the mean wing length is 47 mm, the selection gradient on wing length is β = 0.12/mm, the phenotypic variance for wing length is P = 3.6 mm2, and the heritability of wing length is h2 = 0.27. In addition, we know that the additive genetic covariance between wing and leg length is 0.60 mm2.

Define selection gradient, variance, and heritability using your own words, as if you are explaining these to a freshman biology study.

What is the expected evolutionary change in mean leg length due to selection on wings?

What is the expected evolutionary change in mean leg length due to selection on both wings and legs?

Repeat these calculations to predict what will happen to wing length as a result of the selection on both wings and legs. What do you predict the average wing and leg lengths will be in the next generation?

Why do your predictions in b, c, and d differ? Explain, using evolutionary language.

Is evolution occurring? Describe and explain, using evidence from your calculations.
