You examine dishes of tobacco seedlings, noting seedling color. Each dish represents offspring from a single genetic cross. You know that there is a single genetic trait involved in chlorophyll production that creates the color difference that you are observe. Use the following designations for the alleles:G = chlorophyll production; green seedling (dominant)g = no chlorophyll production; white seedling (recessive) In one dish you count no green seedlings and 91 white seedlings. What are the most probable genotypes of the parents?

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).

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:
