A biologist measures the allele frequencies of pea plants in a very controlled environment. The plants can either have a dominant tall allele (7) or a recessive short allele (t). Which of the following would be a reason that this population is not at Hardy-Weinberg equilibrium? O A. The pea flowers are pollinated at random. OB. There are no mutations in the alleles for height. C. All of the pea plants reproduce exactly once. O D. Tall plants are more likely to survive.​
