Document Summary
Biol 1001 symbiosis lecture week 4 (january 25 29) Chapter 3. 3 3. 5: evolution by natural selection (pg. Because selected traits are passed on to offspring, the frequency of the selected traits increases from one generation to the next. In conclusion: heritable variation leads to differential reproductive success. Biological fitness the ability of an individual to produce surviving offspring. Adaptation a heritable trait that increases the fitness of an individual in a particular environment relative to individuals lacking the trait. ** adaptation increases fitness the ability to produce offspring. Chest x-rays & fluid ejected from lungs showed a case of tb infection. Treated with: antibiotics, doses of rifampin & isoniazid. 2 months later, re-admitted with case of fever, severe cough & laboured breathing. 10 days later, he died of respiratory failure mtb growing actively again and now resistant to rifampin.
