Dr. Mendel asked his BIOL 260 class what their height was and what their
parent's heights were. He plotted that data in the graph below to determine if
height was a heritable trait.
A. Is height a heritable trait? If yes, what is the heritability value? (2 pts)
B. If the phenotypic variation is 30, what is the variation due to additive alleles?

Experiment:
Each team will be provided with 5g of a mixture of acetanilide and salicylic acid. You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below.
Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization.
Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C
Sample C-Cool the third sample in an ice-bath to 0-2 °C
Results:
weight after recrystalization and melting point temp.
A=0.624g,102-115°
B=0.765g, 80-105°
C=1.135g, 77-108
What is the percent yield of A,B, and C.
