A new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-gene locus and that the purple allele (C) is dominant to the pink allele (c). A random sample of 1000 tulips from a large cultivated field yields 847 purple flowers and 153 pink flowers. What is the frequency of the purple and pink alleles in this field population?
A、purple allele frequency = 0.847, pink allele frequency = 0.153
B、purple allele frequency = 0.153, pink allele frequency = 0.847
C、purple allele frequency = 0.82, pink allele frequency = 0.18
D、purple allele frequency = 0.61, pink allele frequency = 0.39
E、purple allele frequency = 0.39, pink allele frequency = 0.61
