(1 point) What stage of meiosis is represented in the diagram below?

(1 point) During spermatogenesis, how many mature sperm cells are produced from one primary spermatocyte?

(2 points) What is the expected genotypic (not phenotypic) ratio for a monohybrid cross between Bb x Bb. (Hint: Use a Punnett square to determine how many of each genotype are expected.)

(1 point) Suppose that in peas, purple flowers are dominant to white flowers, and yellow seeds are dominant to green seeds. If two parents which are hybrid for both traits are crossed (PpYy x PpYy), what is the expected phenotypic ratio?

(1 point) What is the genotype for the individual I-1 in the pedigree below? 

This is a multipart problem. Answer each part (A-D) in the individual spaces provided.   In the gel electrophoresis run of the variants of the TNF gene (alleles TNF 1 and TNF 2), the first two lanes in the gel are the controls for the known alleles. Wells 3-5 are samples for the gene from three individuals (identified as DNA 1, DNA 2, and DNA 3). The DNA samples are stained with a fluorescent dye the glows when exposed to UV light.   (A.) (1 point) Assuming the two alleles are the same size and roughly the same shape, which would have the greater charge, TNF 1 or TNF 2? Answer: [BLANK-1]   (B.) (1 point) If both alleles had the same charge and shape, which would be larger? Answer: [BLANK-2]   (C.) (1 point) Which DNA sample came from an individual that is homozygous for the TNF 1 allele, DNA 1, DNA 2, or DNA 3? Answer: [BLANK-3]   (D.) (1 point) Which DNA sample came from an individual that is heterozygous for the TNF gene, DNA 1, DNA 2, or DNA 3? Answer: [BLANK-4] 

This is a multipart problem. Answer each part (A-B) in the individual spaces provided.   Use this diagram of an animal cell going through nuclear division to answer the next two questions. (A.) (2 points) What stage of the cell cycle is represented in the diagram? Answer: [BLANK-1] (B.) (2 point) What is the name of the specific structure labeled #6? Answer: [BLANK-2]

What is the frequency of the recessive allele (q) if 9% of the population expresses the recessive phenotype?

#3: First, indicate the Brazilian cultural practice, product, or perspective #3. Then write how this compare with cultural practices, products, or perspectives in the U.S. You may write in either Portuguese or English for this activity. 

C. Saudações: Cumprimentar as pessoas. In the culture box on page 7 of your textbook you learned different ways Portuguese-speaking men and women greet each other. In English, cite two types of common greetings in Brazil. Then, compare it to how people greet each other in the United States. Lastly, briefly describe which style of greeting that you are most comfortable with and why? (1 pt. for each type of greeting, 1 pt. for comparison, 1 pt. for describing comfort-level, 1 pt. for logical response; 5 pts. total)   This activity requires the instructor to review the answers to determine the final score.
