In a population of Mendel's garden peas, the frequency of dominant yellow-flowered plants is 50%. The population is in Hardy-Weinberg equilibrium. From this information alone, can you determine the allele frequencies (A = p and a = q)? Why or why not?
Fill in the blank with the appropriate word.
No. The dominant phenotype can be either AA or Aa, so you can't determine allele
frequencies from the genotype frequency.
