FIVE. You have identified a new mutant in Drosophila that defines a gene you call “red.” When mutant it causes the “neck” of the fly (cervical connective) to be red. It behaves as an autosomal recessive mutation with alleles red+ and red-. You suspect it is linked to two known genes on the second chromosome “re” and “ti”. The re- mutation behaves as an autosomal recessive. Homozygous mutant flies fixate on TV reruns, “re+” normal flies avoid TV. The “ti”...

1) We discussed calls in class. A call is a financial instrument that allows the owner of the call to buy a stock at a certain price. ie., if google is selling for $100/share. And I own a call for $105. That means i have the right to buy google at $105 from the institution that sold me the call. Today, I would not use my right to buy at $105, because it would be cheaper to simply by Google...
