All populations are randomly mating and are IN HWE (except question #3 but you still should
be able to calculate the correct numerical answer for all of these questions).
Now, it is usually at this time that someone wants to know or asks, “Dear Dr. Lee, when will
you be posting the answers to these questions??” Answer: I will not be. “WHAT!?!?!?!”, you
say. My musings: I want you and your colleagues to discuss these problems and IF you are
100% confused and thus incapable of attaining these answers then feel free ask your TA or
come by my office.
1. If the RR genotype percentage is .36, what is the frequency of the dominant allele?
2. If the frequency of the recessive allele is .7, what percentage of the population expresses
the dominant allele?
3. If there are ten individuals in a population, 2 are RR, 6 are Rr and 2 are rr, what is “q” at
THIS particular time?
4. If the frequency of the dominant allele is .3, what percentage of the population is
homozygous?
5. If “p” is .6, what percentage of the population is heterozygous?

  1. If the RR genotype percentage is .36, what is the frequency of the dominant allele?
  2. If the frequency of the recessive allele is .7, what percentage of the population expresses the dominant allele?
  3. If there are ten individuals in a population, 2 are RR, 6 are Rr and 2 are rr, what is “q” at THIS particular time?
  4. If the frequency of the dominant allele is .3, what percentage of the population is homozygous?
  5. If “p” is .6, what percentage of the population is heterozygous?

What are p and q for all 4 of these populations and which one is IN HWE?????

    1. P2 2pq q
    • .3 .4.
    • .2 .6.
    • .25 .5.
    • .1 .8.
