The population of Broadshoulder Hawks living on The Hill is undergoing selection for larger talons so that they can more easily incapacitate and eat undergrads that are too absorbed in their phones and have no situational awareness. Which population/s are undergoing directional selection and why?
Homework Answers
Directional selection is a mode of positive selection in which a perticular phenotype is being selected for, causing the alle frequnecy to shift in that direction. In this case, the population of Broadshoulder Hawks are undergoing directional selection for larger talons meaning that the hawks with the larger talons will be chosen and selection will favor the fixation of alleles that confer the large size of the talons. But the human population is also undergoing directional selection. The hawks with the large talons feed on humans that re oblivious to their surrounding. So in humans selection is favoring the humans who are alert and thus is selective for a perticular behavior i.e alertness. So both populations are undergoing directional selection.

Climate change is a threat to the existence of many species.
QUESTION 2 Climate change is a threat to the existence of many species. Which of the following limits to natural selection hinders the adaptation of species to the new climate conditions? The developmental plans of plants and animals are too complex. They cannot cope with the warmer temperatures. Mutations happen so frequently that beneficial alleles change before natural selection can substantially increase their frequency Many species not have gene variants in their gene pool that are beneficial in higher temperatures. Climate change happens so...

According to the Centers for Disease Control and Prevention (CDC), obesity in the U.S. population increased from about 12% in 1991 to about 34% in 2006. The highest increase occurred in 18- to 29-year-olds. Although part of the reason is our increasingly sedentary lifestyle, the principal cause is our overconsumption of abundant processed food products, many of which are high in fat and sugar content. Why do you think fat tastes good to so many people, and is difficult to...

Although the following scenario is hypothetical, it is based on actual facts. Sickle cell anemia is an inherited form of anemia. Those with sickle cell anemia do not have enough healthy red blood cells to adequately carry oxygen to all the cells in their body. Normal red blood cells are flexible and round, and can easily move through the blood vessels. However, in...

According to Robert Trivers, why are men generally larger and more physically aggressive than women? Because women are more reproductively “valuable” than men, hence competition for mates is fiercer among men Because men invest more heavily in reproduction than women Because men secrete more testosterone Trivers’ theory does not speculate on the origin of the sex difference in size and physical aggression Although some women are interested in casual sex (short-term mating), research has suggested that there are differences in...

Q3.3. Recall the prediction: Allele frequencies change by genetic drift equally quickly in large populations and in small populations. Is this correct? Why or why not? Yes. Genetic drift is sampling error, and sampling error is unpredictable, no matter the population size. Yes. Small populations experience more sampling error, but large populations have more reproduction overall, leading to similar rates of allele frequency change. O No. In the ferret experiments, allele frequencies changed more quickly in the small populations than...
