Germinating beans are placed in a thermos with water and allowed to sit for several hours. When you compare the temperature in the thermos with the beans to the temperature in a thermos with just water, the temperature in the thermos with beans:

In fruit flies, body color is either tan or ebony; this trait is controlled by a single autosomal gene, with the dominant allele T = tan, recessive allele t = ebony.You sample a large population of randomly interbreeding flies and find that out of 100 flies, 91 have a tan body and 9 have an ebony body. Assuming that the population is in Hardy-Weinberg equilibrium, how many of the tan flies should be heterozygous (genotype Tt)?

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).
