Five conditions are required to maintain the Hardy–Weinberg equilibrium in a population. Closed population Large population Random mating No net mutations No natural selection If any of these conditions is not being met, the allele frequencies in the population will change, leading to microevolution in the population. Match each of the following scenarios to the Hardy–Weinberg condition that is NOT being met: An increase in antibiotic resistance among bacteria exposed to antibiotics occurs.  Caribou from one herd move to a new area and breed with caribou of a completely different herd.  Among eastern bluebirds, more brightly coloured males breed with more brightly coloured females.   Due to overhunting, there is little genetic diversity in the current population of bearded vultures, which have all descended from a population of only 36 birds.

Five conditions are required to maintain the Hardy–Weinberg equilibrium in a population.

1. Closed population
2. Large population
3. Random mating
4. No net mutations
5. No natural selection

If any of these conditions is not being met, the allele frequencies in the population will change, leading to microevolution in the population.

Match each of the following scenarios to the Hardy–Weinberg condition that is NOT being met:

An increase in antibiotic resistance among bacteria exposed to antibiotics occurs. 

Caribou from one herd move to a new area and breed with caribou of a completely different herd. 

Among eastern bluebirds, more brightly coloured males breed with more brightly coloured females.  

Due to overhunting, there is little genetic diversity in the current population of bearded vultures, which have all descended from a population of only 36 birds.
