Complete the passage with the correct terminology:

Bacteria can become antibiotic resistant through __________. When you take antibiotics, the medicine kills most of the bacteria, but some bacteria might have random mutations that make them stronger and able to survive. These __________bacteria live on and start to reproduce, passing their resistance to their offspring. Over time, more of the bacteria in the population become resistant, making the antibiotic __________ effective. This is why it's important to finish all your antibiotics — stopping too soon could leave behind the strongest bacteria, making infections harder to treat in the future.

Affects small populations more strongly
Usually reduces genetic variation within a population
Happens by movement of individuals or gametes between populations
Can affect populations of any size
Happens by chance (random events like natural disasters or small population size)
Usually increases genetic variation by introducing new alleles
Genetic Drift
Gene Flow
How does independent assortment affect genetic variation?
Mixes genes from parents, increasing offspring diversity.
Keeps genes the same across generations.
Only affects physical traits, not genetics.
Reduces gene combinations in offspring.
What is the role of crossing-over in meiosis?
Produces identical chromosomes for reproduction.
Prevents any genetic variation from happening.
Duplicates chromosomes before division occurs to increase the chromosome options in offspring.
Swaps segments between chromosomes, enhancing genetic diversity.
Why is diversity important in sexually reproducing populations?
Leads to more genetic disorders in populations because the number of genes always change.
Decreases adaptability to new environments and diseases.
Restricts variations within the species.
Enhances survival chances against environmental changes and diseases.
