Natural Selection Flashcards
What must occur for natural selection to happen?
- Over many generations
- Diversity
How does Antimicrobial resistance work?
The misuse and over use of these amicrobial medications help pathogens develop a resistance of them
Selective pressures
Environmental factors that influence which individuals of a population are more likely to survive and reproduce
Example of Selective breeding
Domesticated animals, such as dogs, crops and livestock
Fitness
Measures an organisms ability to survive and reproduce
Is AMR an example of natural selection? Explain.
Yes, it is because the pathogens were able to adapt and pass on a specific allele that can make them immune to these medications.
Examples of selective pressures
Predators, disease, climate, availability of resources
Biotic vs Abiotic
Biotic - living things eg. predators
Abiotic - non-living things eg. temperature
Natural selection
a process that results when characteristics pf organisms change over many generations because individuals with certain traits survive, reproduce, and pass on their alleles.
What is an organism going to look like if it has high fitness?
Organism will survive, reproduce, pass its traits and offspring will survive and reproduce
Artificial selection
Certain traits are selected but selective pressures are coming from humans. “Selective Breeding”
Antimicrobial resistance
Happens when pathogens like bacteria and fungl develop the ability to evade the medications used to kill them.
