This is a multipart problem. Answer each part (A-C) in the individual spaces provided.   During the lab, paper chromatography was used to separate plant pigments. The results are shown below. (A.) (2 points) Which pigment has the greatest affinity for the paper, A, B, C, or D? Type only a capital letter for the pigment in the space provided.   Answer for Part A: [BLANK-1]   (B.) (2 points) Calculate the Rf value for the pigment labeled C. Round answer to 2 decimal places.   Answer for Part B: [BLANK-2]   (C.) (2 points) If another pigment, other than the ones present in this experiment, was present and had an Rf value of 0.56, where would this pigment be located on the chromatography paper relative to the others? Type only one capital letter that identifies the specific pigments in each space.   Answers for Part C: This other pigment would be located between Pigment [BLANK-3] and Pigment [BLANK-4]. 

(2 point) Where do the light reactions of photosynthesis occur? Answer: [BLANK-1] 

(2 points) What stage of mitosis is represented in this animal cell?   Answer: [BLANK-1] 

(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]
