Name______________________ Class unique number_____________ Practice Problems on Allele Frequencies and Population Genetics 1. If the alleles for a certain trait (single locus, simple dominance) had frequencies of p = 0.7 and q = 0.3, then (a) what is the frequency of homozygous recessive individuals? q 2 =_________. (b) What is the frequency of heterozygous individuals? 2pq =________. (c) If this trait was determined for 100 individuals randomly chosen from the population, how many would show the recessive trait?__________ 2. Within a population of butterflies, the color brown (B) is dominant over the color white (b), and 25% of all butterflies are white. Given this simple information, calculate the following: (a) the percentage of butterflies in the population that are heterozygous (b) the frequency of homozygous dominant individuals. 3. In a population of mice, 4% (0.04) of the individuals are albino (phenotype showing simple recessive trait, so their genotype is aa ), and the rest are all agouti brown (phenotype showing the dominant trait A ).

    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.
