Michael Romero (Body size, performance and fitness in Galápagos marine iguanas, Integrative and Comparative Biology 43 [2003]:376-86) measured the snout-to-vent (anus) length of Galápagos marine iguanas and observed the percent survival of different-sized animals, all of the same age. The graph shows the log snout-vent length (SVL, a measure of overall body size) plotted against the percent survival of these different size classes for males and females. Survival (%) 100- 80- 60- 40- 20- 0+ 1.9 T 2 2.1 2.2 2.3 2.4 2.5 2.6 2.7 Log SVL (mm) 19) Examine the figure above.

- 24) Use the following information to answer the question below. Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are determined (see table) and used to determine the actual allele frequencies in the population. TT 0.49 Tt 0.42 tt 0.09 Refer to the table above. Is this population in Hardy-Weinberg equilibrium? A) Yes. C) No; there are more homozygotes than expected. B) No; there are more heterozygotes than expected.

Thank you: The Polymerase Chain Reaction (PCR) reaction consists of three steps denaturation, hybridization, and elongation. Please describe what occurs in the annealing step of the PCR reaction. (I think annealing step is hybridization). What are the other two steps of PCR, and what are their functions? Next, suppose the Tm for the two primers being used are 54C for Primer A and 67C for Primer B. Regarding annealing step temperature, I have the following choices for the temperature used during the annealing step:(a) 43C (b) 49C (c) 62C (d) 73C Which temperature/temperatures should I choose? What is the corresponding correct explanation, and why would I not use the other temperatures? Have a good day!arrow_forward
