23. Alarge population of plants was surveyed for the frequencies of the alleles of a specific gene. The frequency of the dominant allele A was 0.8 and the frequency of the recessive allele a was 0.2. Five years later, the frequencies of A and a were still 0.8 and 0.2 respectively. A third survey was done five years after that (ten years after the first) and the allele frequencies were now 0.6 and 0.4 for A and a, respectively. Explain what these results mean in relation to whether the population is in Hardy-Weinberg equilibrium and ,fi 't o'\ /\a ,, UL t1- 1,$ whether it is evolving.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
