Unformatted text preview: Chromosome Chromatid a) Anaphase II ___________ __________ b) Prophase ___________ __________ c) Telophase II ___________ __________(after cytokinesis) d) Metaphase I ___________ __________ 3. A cross between two pea plants, both of which grew from yellow round seeds, gave the following numbers of seeds: 156 yellow round and 54 yellow wrinkled. What are the genotypes of the parent plants (yellow is dominant trait)? (4pts)? 4. Three mutants were isolated in a normally red fungus. The mutations are found to be in different genes. Mutant A (A-) is white, mutant B (B-) is colorless, and mutant C (C-) is pink. Through crossing, lab technician obtained the following double mutants and the corresponding phenotypes, A-B-showed colorless and A-C-showed white color. Please use above phenotypes to figure out the pathway, both colors and enzymes: (6 pts)--------> --------> ---------> Red pigment Enzyme Enzyme Enzyme What color will B-C-double mutant look like? (1pts)...
