The article "Structural Performance of Rounded Dovetail Connections Under Different Loading Conditions" (T. Tannert, H. Prion, and F. Lam, Can J Civ Eng, 2007:1600—1605) describes a study of the deformation properties of dovetail joints. In one experiment, 10 rounded dovetail connections and 10 double rounded dovetail connections were loaded until failure. The rounded connections had an average load at failure of 8.27 kN with a standard deviation of 0.62 kN. The double-rounded connections had an average load at failure of 6.11 kN with a standard deviation of 1.31 kN. Can you conclude that the mean load at failure is greater for rounded connections than for double-rounded connections?

Mendel’s Principle of Independent Assortment A. 4 different gametes produced B. 50% alignment pattern 1. equal proportions II. Gene Linkage A. gene linkage 1. genes close together on same chromosome tend to be inherited together and are passed as a unit 2. they do not sort independently III.Demonstration of Linkage and Recombination A. mutations can be inherited dominantly or recessively 1. curly allele is dominant to wild type 2. Cy = curly wings 3. Cy+ = straight wings 4. capital C tells me curly mutation is dominant to wild type 5. purple allele is recessive to wild type IV. Morgan’s Test Cross A
