26. Analyze the results of a cross between two organisms that are both heterozygous for two different genes (AaBb). Use a Punnett square to evaluate the possible genotypes. (1) List all the genotypes from your Punnett Square in the answer space. (2) Determine how many phenotypes can be produced in the offspring. (3) Determine the probability of producing offspring with the aabb genotype. (3 points) 27. Explain why the daughter cells produced by meiosis are genetically different from each other, whereas the daughter cells produced by mitosis are not. (2 points) 28. Describe the possible consequences of a mutation on an organism. Describe an example for each consequence you mention. (3 points) 29. Why is gene regulation necessary in the development of multicellular organisms? Use a specific example to support your argument. (3 points) 30. Suppose you are a scientist trying to help people who cannot produce an enzyme needed for proper digestion. How could you use genetic engineering techniques to make transformed bacteria that produce the enzyme? (3 points)

Biology's a subject, that really, simply requires you to read the book. Not like the other subjects, like Physics, Chemistry, "Writing", Mathematics.

28  if a city butterfly, originally brown, get a mutation making the color of her wings being white, the consequence may be that she will more vulnerable to predators, as she can't camouflage anymore in the city environment

29  For example, gene regulation is necessary to cell specialization, creating cells with different characteristics at different positions. (study the rest at http://www.ncbi.nlm.nih.gov/books/NBK21046/ )

30  First you clone the gene of interest via PCR (Polymerase chain reaction).  you insert the gene in a vector, called plasmid, using restriction enymes.  then you insert the recombinant plasmid in the bacteria, using electrotransformation. This is the way to produce, for example, insulin protein to be used by diabetic people.
