In the example of the wildflower population, if there were 250 plants with red flowers CRCR , 200 plants with pink flowers CRCW , and 50 plants with white flowers CWCW , what would be the frequency of the CR allele? Assume the total population remains 500 plants .

  • A: 0.5
  • B: 0.6
  • C: 0.7
  • D: 0.8

Explanation

Total number of alleles in the population = 500 plants 2 alleles/plant = 1000 alleles. Number of CR alleles from CRCR plants = 250 plants 2 alleles/plant = 500 CR alleles. Number of CR alleles from CRCW plants = 200 plants 1 allele/plant = 200 CR alleles. Total CR alleles = 500 + 200 = 700. Frequency of CR allele = 700 / 1000 = 0.7.
