In a laboratory experiment of sexually reproducing plants, a certain trait is determined by a single gene. the dominant allele has complete dominance over the recessive allele, resulting in two different phenotypes. scientists created a new population of this plant by crossing 51 homozygous dominant individuals with 49 homozygous recessive individuals. the following results are from the first five generations of this population: answer each part of this question completely in the space provided. on the basis of the data, propose an explanation for the phenotypic changes from generations 1 to 3. do you think this population is in hardy-weinberg equilibrium? support your answer. what are two possible conditions that can disrupt a hardy-weinberg equilibrium?
