A meadow is home to a population of plants of a particular species. Among these individuals are 125 plants that have red flowers and 375 plants that have white flowers. The allele of the flower color gene that produces red flowers (R) is completely dominant over the white flower color allele (r). What is the total number of flower color alleles in this population of plants? a- 500 b- 2 c- 375 d- 1,000 e- 4
