In a hypothetical situation, a certain species of flea feeds only on pronghorn antelopes. In the western United States, pronghorns and cattle often associate with one another in the same open rangeland. Some of these fleas develop a strong preference for cattle blood and mate only with other fleas that prefer cattle blood. The host mammal can be considered as the fleas’ habitat. If this situation persists, a new species can evolve. This would be an example of what?

List the five Hardy-Weinberg assumptions and give one sentence for each on how they could be violated.

Which mechanism would reverse speciation?

Give two differences and two similarities between Meiosis II and Mitosis.

Dwarf Cavendish bananas are the most common banana on grocery shelves. They are triploid, meaning that they have three sets of chromosomes. Because of this, meiosis and creation of gametes is not possible, and cultivation depends on vegetative propagation through mitotic divisions. This information leads to which of the following conclusions?

In an environment in which members of a population compete with each other for resources, a change occurs that selects against members that exhibit a particular dominant trait (the trait exhibits complete dominance). Which of the following graphs best depicts the trends in genotypic frequencies that would be expected to occur over time?

As bottlenecks go, they don’t get much narrower: based on a genetic study, scientists found that Florida panthers, nearly wiped out in the early 20th century, dropped to a population size of as little as six animals. Scientists compared DNA samples taken from museum specimens from the 19th century with samples from the 1980s. They found that the late 20th century cats had only a third of the genetic diversity of their 19th century ancestors. The bottleneck caused widespread health defects in the wild cats, including undescended testicles and poor sperm quality. A “genetic rescue” experiment was launched in Florida in 1995, when eight female pumas from Texas were introduced to the Florida panthers. The question is: which evolutionary mechanism is purposefully used in this “genetic rescue”?

Hemophilia A is a blood disorder that slows the blood clotting process, which can be dangerous after injury. The condition is caused by a recessive allele of a gene on the human X chromosome. What is the probability for a woman to have this condition?

True or False: Ethical communicators are empathetic and strive to understand and respect what other people think and feel?
