In pea plants, the allele for yellow peas is dominant to the allele for green peas. A sample of 100 peas contained 84 yellow and 16 green peas. What is the frequency of the yellow allele in this population? A 0.36 B 0.40 C 0.60 D 0.84 15. An experiment investigated the effect of an insecticide on local wild bee populations. Scientists sampled each species of bee in proportion to the contribution its population size made to the total number of bees of all species present in the area. What name is given to this type of sampling strategy? A Random sampling B Stratified sampling C Systematic sampling D Point count sampling
