The following symbols are used in this narrative:G = allele for green pea podsg = allele for yellow pea podsIn his studies Mendel looked at the inheritance of pea pod color.  When he performed monohybrid crosses (Gg x Gg) and then grew the offspring he found the following:428 plants making green pods152 plants making yellow podsPerform a chi-square test comparing the predicted numbers for Gg x Gg with his results (you will have to calculate the predicted numbers yourself). Table of Chi-Square Numbers Degrees of Freedom 90% 80% 70% 50% 30% 20% 10% 5% 1% 1 0.016 0.064 0.148 0.455 1.074 1.642 2.706 3.841 6.635 2 0.211 0.446 0.713 1.386 2.408 3.219 4.605 5.991 9.210 3 0.584 1.005 1.424 2.366 3.665 4.642 6.251 7.815 11.341  The chi-square (χ2) when you compare your result to the expected result is:

In the fruit fly Drosophila melanogaster, eye color is influenced by an X-linked gene.  Also, females are XX and males are XY for sex chromosomes.  The alleles for eye color work as follows: XR = dominant; red eyesXr = recessive; white eyesY = Y chromosome; male, no eye color gene on this chromosomeYou examine a vial of 100 flies that are all offspring from a single genetic cross. You find both red-eyed males and white-eyed males but only red-eyed females.  The genotypes of the parents were apparently:

A dialysis bag that is permeable to water but not NaCl is partially filled with 30% NaCl solution, closed, and then weighed.  Next, it is put into a beaker containing 10% NaCl solution and allowed to sit for 1 hour.  If you then weigh the dialysis bag and its contents, you should find that the weight has:

The cells below are both _ and _ .

A population of four o’clocks is being studied to see if it is in Hardy-Weinberg equilibrium.  Recall that in four o’clocks flower color is determined as follows:RR = redRr = pinkrr = white Let:p = frequency of R alleleq = frequency of r allele You count 100 plants total: 36 plants with red flowers, 48 plants with pink flowers, and 16 plants with white flowers. What is the value of “q” (the frequency of r) for this population?
