Three linked autosomal loci were studied in squash: flowering time (late vs. early), fruit shape (elongate vs. ovate) and stem length (long vs. short). pure breeding early flowering, elongated squash with long stems were mated to pure breeding late flowering, ovated squash with short stems. the f1 were testcrossed and the testcross progeny are given below. flowering time fruit shape stem length number late elongate short 612 early elongate short 66 early elongate long 1217 late elongate long 362 late ovate long 80 early ovate long 653 early ovate short 370 late ovate short 1305 use the map to answer the questions below. fruit shape locus b locus c r1 r2 how many progeny did you look at for this experiment

Two students are working together on an experiment that measures the effect of different liquid fertilizers on the thickness of plants’ stems. which is most likely to result in the greatest amount of error in their scientific experiment? a. one student measures the plant stem widths by using calipers. the other student measures the widths of the same plant stems again by using a different pair of calipers. b. one student measures the plant stem widths by using calipers. the other student types the measurements as they are taken into a computer spreadsheet. c. one student weighs liquids for the experiment by using a calibrated scale. the other student weighs liquids for the experiment by using a different calibrated scale.
