Mader, Michael Windelspecht Publisher:McGraw Hill Education What do you think these scientists concluded about the function of the Pitx1 protein after carrying out this experiment?a) What do you think these scientists concluded about the function of the Pitx1 protein after carrying out this experiment? Because the mice lacking a functional Pitx1 protein had miniaturized hind limbs, Pitx1 appears to play a function in hind limb development in mice.
How did the stickleback fish population end up cut off from the ocean?As more and more ice melted, the land that had been depressed by the weight of the massive ice sheets became elevated, and the connections between some of the lakes and the ocean were cut off. Researchers think that stickleback populations became trapped in these lakes and adapted to living exclusively in fresh water.
What is the purpose of the spines of sticklebacks?The many stickleback populations underwent disparate and parallel evolutionary changes, among them partial or complete loss of their pelvic spines. These spines are thought to protect the fish from being devoured by predators.
Why is the threespine stickleback a model organism for studies in evolution list at least two reasons?The threespine stickleback is an appropriate model organism for studying the effects of host genetic background on microbial community because wild populations exhibit genetic variation that is comparable to that of human populations.
