An alien cell is 2n=10. Chromosomes 1 and 2 carry the genes for eye number and eye color.Cyclops is recessive to two eyes, and green is recessive to purple.Chromosomes 7 and 8 carry the gene for mind control. Mind control is dominant over normal brain.Chromosomes 1 and 2 are homologous, and so are 7 and 8.You are given a cell culture of an alien that is homozygous recessive for the cyclops gene and heterozygous for green color. It is also heterozygous for the mind control gene, which is located on a separate chromosome. Make a sketch to show how this alien’s chromosomes could be arranged during anaphase of mitosis Explain how different this cell would look during anaphase I of meiosis? What is the significance of this difference?

The passing grade is set at 50%. Unluckily for you, you haven’t been to a single class before this, nor have you ever opened the textbook. Actually, you can’t even say for sure who the guy is at the front of the class. You will have to guess the answer on all the questions. What is the probability that you will pass the exam?
