You are working in a lab that studies stickleback fish. These fish normally have three spines that occur on the back of the stickleback. One day you notice that a young stickleback has no spines on its back but instead has three spines growing out of the top of its head! (answer both questions) question 1: A mutation in what type of gene is probably the cause of this unusual situation? Why? question #2: would you expect the proteins that make the spines to be different in the mutant fish compared to a wildtype fish. Why or why not?

Suppose that a mutation resulted in a tapeworm that did not have hooks. Assuming this tapeworm was a human parasite, what is the most likely explanation of the effect might this have? The tapeworm would spread throughout the human body. The tapeworm would complete its entire life cycle inside the human host. The tapeworm would not remain in the digestive tract very long. The tapeworm would not be able to enter the human body. The tapeworm would reproduce more to compensate for a lack of hooks.

On an island with no large predators, some ducks are born with a mutation that gives them stubby little wings. These ducks can’t fly, but there’s really no need to fly since there are no predators. In fact, they have an advantage because they don’t have to eat as much to support those big wings like the other ducks. Over time, the flightless ducks reproduce better than the regular ducks, and eventually all the regular ducks die out. What characteristic of life is being demonstrated here?

The null allele is defined as the allele that is caused by the mutation of the gene. The resulting copy of the gene is nonfunctional. There is complete lack of associated gene product due to the mutation and the product will not function properly.

Solution Summary: The author explains that the null allele is produced in the zebrafish due to the frameshift mutation, not by missense or silent mutations.
