Answer:
Pulmonary plague, septic plague and bubonic plague.
Explanation:
So, Yersinia pestis is a rod-shaped bacterium. This microorganism can affect humans through the flea Xenopsylla cheopis. Then, the disease can manifest in three ways: pulmonary plague, septic plague or bubonic plague.
Pneumonic plague is the form of the disease that infects the lungs and its symptoms begin abruptly two to three days after exposure to bacteria. Patients have a high fever, chills, fast heart rate and often severe headaches.
Another form of the disease is the septicemic plague and the infection spreads in the bloodstream. The most common symptoms are nausea, vomiting, diarrhea, and abdominal pain.
Finally, bubonic plague, or also known as the minor plague, is a milder form of the disease that affects the lymphatic system and its symptoms are swollen lymph nodes, fever, headache, and exhaustion.
Genetic diversity decreased as the human population migrated from Africa to other continents because each migration had a chance to obliterate one or more genetic variants.
<h3>
What is genetic diversity?</h3>
The term "genetic diversity" refers to the entire gene pool that a population or species possesses in a specific habitat.
During migration, genetic diversity is essential for adjusting to new environmental situations.
The genetic diversity decreased when the human population migrated from Africa to other continents since each migration had a chance of bringing with it one or more genetic variants.
