Consider a mainland-island migration scenario where two alleles are segregating and the observed frequencies of heterozygotes are such that H=.32 for the mainland and H=.5 for the island. (These are the values of heterozygosity) What are Pisland and Pmainland? Assume Hardy-Weinberg equilibrium. Equation given was Pisland = Pmainland + ( […]

Question: To see patterns in the data from an experiment like this, it is helpful to graph the data. A bar graph is used instead of a line graph because each type of liver cell was independent of the others. But first, you must determine which variable should go on each […]

a) Genetically modified organisms (GMOs). What is the purpose genetic engineering of crop plants and domestic animals? Briefly explain how GMOs are created. What foods in your supermarket contain GMOs? Are foods that contain GMOs safe for human consumption? What types of regulations exist for these foods? Clearly explain your […]

In D. melanogaster, the alleles dp+ and dp determine long versus short wings, and e+ and e determine gray versus ebony body. A dihybrid cross was carried out to produce flies homozygous for both dp and e. The following phenotypes were obtained in the F2 generation: long wing, gray body […]
