Complete the Punnett Square on page 104 and Part B on page 105. Transfer all the data to Data Table1 on page 106 Determine Frequency of Class Data Below you will find a spreadsheet of the "class" data, use this to complete data table 2. Remember, the class is a total of 24 students, to calculate frequency use the genotype with the highest frequency for each characteristic and divide that number by 24. Don't forget to answer the quesțion on the bottom of page 107!

For instance, if the class results for sex determination were seven XX combinations and three XY combinations, the frequency would be calculated like so: Frequency XX = 7/10 = 0.70 Frequency XY = 3/10 = 0.30 %3D Notice that the frequencies always add up to 1. Determine the frequencies for each trait. Use the highest frequency for each characteristic to determine the traits of an individual created by the entire class. Record your data in Table 2. Table 2. Genotypic and Phenotypic Description and Frequencies of Allelic Combinations of an Individual Created through Rolling of Dice-Class Results. Highest Frequency Characteristic Genotype Phenotype Gender-male or female Eyebrows-unibrow or two separate Eye shape-round or almond Hitchhiker's thumb-yes or no Earlobes-attached or detached Tongue roll-yes or no Widow's peak-yes or no Face shape-square, round, oval Eye color-blue, brown, green Chin shape-square, round, pointed Hair color-brown, blonde, red Hair texture-curly, wavy, straight 1. Look at the results of your first Punnett square for sex determination. You should have come up with 50% females and 50% males (or a frequency of 0.50 for each sex). How does that compare to the frequency of males and females generated by the class? 107
