A population of birds contains 16 animals with red tail feathers and 34 animals with blue tail feathers. Blue tail feathers are the dominant trait. What is the frequency of the blue allele? (Round to the nearest thousandth)

frequency of the dominant allele in the population ... 2pq = frequency of heterozygous individuals. A population of rabbits may be brown (the dominant phenotype) or white (the recessive phenotype). Brown rabbits have the genotype BB or Bb. White rabbits have the genotype bb.
