In a two factor test cross you calculated that two genes were 60 map units apart. This is most likely an underestimate of the actual distance due to:

Female fruit flies homozygous for the X-linked white-eye allele (XWXW) are crossed to males with red eyes (XW+Y). On rare occasions, an offspring is a male with red eyes. This rare offspring is most likely ( _______) due to non-disjunction during (                  ). 

In fruit flies, straight wings (S) is dominant to curved wings (s). Recently, you have discovered a new gene in flies that exists in two alleles. The allele designated L causes large heads and the l allele causes small heads. These genes are autosomal and follow a Mendelian pattern of inheritance. You begin with two true-breeding strains, straight wings with small heads and the other curved wings with large heads. All of the F1 offspring have straight wings with large heads. You then cross the F1 offspring to flies with curved wings and small heads and obtain the following results. 187 Straight wings, small heads   60 Curved wings, small heads 197 Curved wings, large heads   56 Straight wings, large heads 500 Total F2 offspring Note:     TABLE 2.1 Chi Square Values and Probability   Degrees of Freedom   P ∙ 0.99   0.95   0.80   0.50   0.20 Null Hypothesis Rejected 0.05           0.01 1 0.000157 0.00393 0.0642 0.455 1.642 3.841 6.635 2 0.020 0.103 0.446 1.386 3.219 5.991 9.210 3 0.115 0.352 1.005 2.366 4.642 7.815 11.345 4 0.297 0.711 1.649 3.357 5.989 9.488 13.277       To conduct a chi square analysis to determine if these two genes are linked, what is your hypothesis?

Match the correct definition to its term

Indicate which aqueous solution has the slowest evaporation rate.

The vapor pressure of an aqueous solution is found to be 24.9 mm Hg at 25°C. What is the composition of the solution (in terms of mole fraction of solute)? The vapor pressure of water is 25.756 mm Hg at 25°C.

The vapor pressure of a substance in solution depends only on

Which solution will have the lowest osmotic pressure when measured against pure water?

The following figure shows four mixtures made from different liquids. Which mixture is immiscible?

Calculate the pressure that must be applied to achieve reverse osmosis of 0.504 M NaCl separated by a semipermeable membrane from a solution that is 0.0020 M in NaCl at 22 oC.R=0.08206 L.atm/mol.K
