ALLELE FREQUENCIES FROM GENERATION TO GENERATION. We now examine what happens to allele frequencies over time - from generation to generation, using population A as our example. Using the Punnett square below, simulate a generation of random mating in population A. This will allow you to determine the allele and genotype frequencies in the next generation. We number the initial generation "0" and the next generation "1". To indicate which population we are dealing with we will call them generations A0 and A1. The allele frequencies which you calculated in Table 1 (the previous question) are the frequencies of the gametes that combined to make the individuals n the sample (generation A0). All things being equal, they will also be the frequency of the gametes produced by these individuals. Fill in the table with both the genotypes of the next generation (A1) and their expected frequencies. Population A Male gametes M (0.3) N (0.7) MM V MN V M Female (0.3 freq = 0.09 freq = gametes MN V NN V (0.7)freq = freq = 0.49 What are the genotype frequencies in generation A1? Genotype MM MN NN Frequency What are the allele frequencies in generation A1? Allele M N Frequency

Pitcher plants can take many forms. You are interested in understanding the genetic control of pitcher formation in pitcher plants. Which of the following is not likely a result you would expect from your QTL study? AV O a. Variation in pitcher size in your F2 population does not exceed that of your parental generation. O b. You were able to reconstitute the phenotypes of the parental generation by selectively breeding F2 individuals. O c. The variation in phenotypes is greater in the F1 population compared to the F2 population. O d. The phenotypes you are interested exhibit a typical Mendelian inheritance.

suppose two alleles exist for gene A in a population of fruit flies.  Alleles "A" is dominat over allele "a".  Suppose the frequency of the "A" allele = 0.4, calculate the expected frequency of allele "a" - give answer as a decimal.

Applying the Hardy-Weinberg equilibrium. 81% of the individuals are homozygous for a recessive allele. What percentage of the individuals would be expected to be heterozygous for this locus in the next generation?
