Final answer:
The initial question data provided appears to be incorrect, but assuming the FPH is 6400 and individual pick rate is 400, the number of pickers required would be 16. The correct option is b.
Step-by-step explanation:
The question seems to be asking for the number of pickers required based on a given 'Fruits Per Hour' (FPH) rate and an individual pick rate. However, the information provided in the question appears to be incorrect or not relevant to the question posed.
The options provided (a. 64 genotypes; 16 phenotypes, b. 16 genotypes; 64 phenotypes, c. 8 genotypes; 27 phenotypes, d. 27 genotypes; 8 phenotypes) correspond to terms used in genetics, not mathematics related to calculating the number of pickers required.
Assuming the FPH (total fruits to be picked per hour) is 6400 and the individual pick rate is 400 fruits per hour, we would calculate the number of pickers needed by dividing the total FPH by the pick rate per individual picker.
The correct calculation would be 6400 fruits per hour / 400 fruits per hour per picker = 16 pickers. The correct option is b.
